Abstract: PROBLEM TO BE SOLVED: To deter display light from a liquid crystal display device display unit becoming hard to see under the influence of external light in a display device for automobile which has a touch panel and the liquid crystal display unit combined. SOLUTION: An uneven part is formed on an external surface of a polarizing plate 3 of the touch panel 1 and an uneven part is formed on an external surface of a polarizing plate 6 of the liquid crystal display unit. Consequently, external light which is incident on the touch panel 1 is diffused by the uneven part of the polarizing plate 3 of the touch panel 1 and the uneven part of the polarizing plate 6 of the liquid crystal display unit. Consequently, the display light from the liquid crystal display unit 2 arranged behind the touch panel 1 can be deterred from becoming hard for an observer to see. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To suppress display light from a display device from becoming hard to see due to the influence of external light in the combination of a touch panel and the display device. SOLUTION: A rugged part is formed on the outer surface of the polarizing plate 3 of the touch panel 1 and the rugged part is formed on the outer surface of the transparent electrodes 1c and 1d of the touch panel. Thus, the external light made incident on the touch panel 1 is diffused by the rugged part of the polarizing plate 3 of the touch panel 1 and the rugged part of the transparent electrodes 1c and 1d. Thus, the display light from a liquid crystal display device for instance arranged on the rear side of the touch panel is suppressed from becoming hard to see for an observer.

Abstract: PROBLEM TO BE SOLVED: To make injected liquid crystal not to creep into the gap between partition walls and to prevent a liquid crystal cell from having display unevenness by connecting partition walls between both electrode substrates at respective end parts on an opposite seal part. SOLUTION: Partition wall bodies 40 are coupled by a rear wall 42 at rear end parts 41a of respective partition walls 41. Even if liquid crystal parts which flow in between a left seal part 32 and a left partition wall 41, and a right seal part 33 and a right partition wall 41 enter the gap between the rear wall 42 and rear seal part 34, they are cut by the rear wall 42, so that they will not creep into the part between partition walls 41. The respective liquid crystal parts flowing in between the left seal part 32 and right seal part 33, and partition walls 41 and respective liquid crystal parts which flow in between adjacent partition walls 41 flow separately and are injected into the cell. The liqiud crystal parts which are different in injection speed never come into contact with each other, and consequently orientation disorder of smectic liqiud crystal which is easily caused at the contact border between the liquid crystal parts injected at different speed can be prevented. Consequently, the liquid crystal cell has no display unevenness.

Abstract: PROBLEM TO BE SOLVED: To easily produce a liquid crystal electro-optical element using a ferroelectric liquid crystal which shows first to third stable states according to electric fields, by heating the ferroelectric liquid crystal to change into an isotropic liquid, filling the space between substrates with the isotropic liquid, and cooling the liquid to change into a chiral smectic phase. SOLUTION: A ferroelectric liquid crystal 6 in which the molecular orientation shows different first to third stable states when no electric field is applied or an electric field in one direction or an electric field in other direction is applied, respectively, is heated to obtain an isotropic liquid. The obtd. isotropic liquid is supplied to fill the space between a pair of electrode substrates 1, 2 and cooled to obtain a chiral smectic phase of the ferroelectric liquid crystal 6. By changing the liquid crystal into an isotropic liquid, it can be easily supplied to fill between the electrode substrates 1, 2. By cooling after filling, the ferroelectric liquid crystal 6 is changed into a chiral smectic phase having desired three states. The cooling process is preferably carried out at 0.1 to 1.0 deg.C/min cooling rate.

Abstract: PROBLEM TO BE SOLVED: To obtain such a threshold that transmittance of light begins to change at specified absolute voltage or higher by specifying the relation of pretilt angles and reverse tilt given to each of a first electrode substrate and a second electrode substrate. SOLUTION: When the voltage applied on both electrode substrates 11, 12 is low, liquid crystal molecules do not rotate. When a specified high voltage is applied, liquid crystal molecules 13a (negative side liquid crystal molecule) on the negative side of the center line of a ferroelectric liquid crystal 13 rotate in the opposite direction to the rotation direction of liquid crystal molecules 13a (the other side liquid crystal molecules) on the other side of the center line of the liquid crystal 13. Therefore, the negative side liquid crystal molecules collide with the other side liquid crystal molecules near the center line, which results that the energy loss in the liquid crystal 13 is largely increased compared with the case of the negative liquid crystal molecules rotating in the same direction as that of the other side liquid crystal molecules. Namely, each molecule 13a of the liquid crystal 13 does not rotate when the voltage applied on substrates 11, 12 is low, but just begins to rotate when a specified high voltage is applied. This means the liquid crystal 13 has a sharp threshold.

Abstract: PROBLEM TO BE SOLVED: To appropriately prevent sealant from penetrating through the edges of barriers into display area in an organic electroluminescent display device having barriers of which sealing plate is attached with sealant.
SOLUTION: On a substrate 1, a lower electrode 2, an organic layer 3 including a light-emitting layer 3b made of organic electroluminescent material, and an upper electrode 4 are layered in this order to form a laminate 5. Two or more stripes of barriers 7 are formed to section the organic layer 3 and the upper electrode 4 and isolate each upper electrode 4 sectioned with the barriers. On the outside of edges of the barriers 7, a wall member 8 extending in the direction perpendicular to the barriers 7 is formed to enclose each of adjacent barriers 7.

Abstract: PROBLEM TO BE SOLVED: To stably provide an organic EL (electroluminescence) element having a long luminance lifetime.
SOLUTION: A method for manufacturing the organic EL element includes a step of sequentially forming a lower electrode layer made of an ITO (indium tin oxide), an organic layer containing an organic EL material and an upper electrode layer on a substrate. In this method, a surface treatment of the lower electrode layer is performed to set a carbonyl compound existing on a surface of the ITO, to a specified amount or less at a surface state of the ITO immediately before the organic layer is formed. It means to set the carbonyl compound to the specific amount or less that in a spectrum of the surface of the ITO obtained by an XPS (X-ray photoelectron spectroscopy) analyzing method, a ratio (P2/P1) of an oxygen peak P1 originating from an In
2 O
3 present at 530 eV and the peak P2 originated from C=O present at 532 eV becomes 0.43 or less, where the peaks P1, P2 are among the peaks P1, P2 and P3 obtained by waveform separating a peak P0 originating from O1s by a curve fitting method.

Abstract: PROBLEM TO BE SOLVED: To provide the long-life connection member which can obtain an excellent electric connection with a terminal to be connected without deforming or flawing the terminal to be connected and the illumination device which turns on a display panel for display by applying a driving signal to the connection terminal of the display panel through the connection member. SOLUTION: A connection sheet 1 as the connection member is formed by weaving flexible fiber 2 having its surface coated with a conductive material or covering a foaming core material 4 made of a pyramidal foaming elastic material with woven conductive cloth 3 and sticking the conductive cloth 3 on the foaming core material 4 with an adhesive 5. Namely, the elasticity of a mat type sheet obtained by gathering flexible fiber is hard to decrease, so an excellent connection with the connection terminal of the sheet can be maintained in its initial state for a long period to obtain a long-life connection member. Further, the surface of the fiber is coated with the conductive material, so its electric resistance is low and the excellent electric connection with the connection terminal can be obtained.
