PURPOSE:To improve the percentage modulation of recording sensitivity and recording signal by constituting a recording medium in such a way that the light absorptive layer thereof exists between the conventional reflecting layer and a noval layer having increased reflectivity. CONSTITUTION:A recording medium 1 has a substrate 2 made of glass having 0.2mm. thickness and 1.5 refractive index. The 1st reflecting layer 3 consisting of a ZnS film deposited by evaporation to have 860Angstrom thickness and 2.3 refractive index is provided as a coating layer having increased reflectivity on one surface of the substrate 2. A light absorptive layer 4 as a recording layer is provided on the exposed surface of the layer 3. The layer 4 is formed by mixing a spiropyrane compd. exhibiting a high absorption characteristic at a >=700nm wavelength region, i.e., 5'-methoxy-1'-n-hexyl-3',3'-dimethyl-6-nitro-8-methoxy spiropyrane and a vinyl chloride/vinylidene chloride copolymer at 1:2 by weight, dissolving the mixture in a solvent and forming the layer by spinner coating. The 2nd reflecting layer 5 consisting of an Ag layer deposited by evaporation to have 1,000Angstrom reflectivity and 0.85-15.35 refractive index is provided as a light reflecting layer on the exposed surface of the layer 4.

Abstract:
PROBLEM TO BE SOLVED: To solve a problem that an organic EL material of powder form is hard to handle and its characteristics are deteriorated promptly if exposed to the atmosphere. SOLUTION: The organic EL material is handled in a morphology of an organic EL element material 11 in which the organic EL material 12 of powder form is filled and sealed in an ampul 13 of glass. Then, when an organic layer is formed on an element forming substrate using a vacuum vapor deposition device, the organic EL element material 11 is input into a deposition source and then, in the process of reducing pressure of the vacuum chamber, the ampul 13 is ruptured by pressure difference of inside and outside, thereby the exposed organic EL material 12 is heated and evaporated.

Abstract:
PROBLEM TO BE SOLVED: To provide an aligning system and method which enable easy and quick registration of two substrates. SOLUTION: This device first moves drive panel 20 in X and Y axial directions by using the X and Y stages to make the position of the specific alignment mark M20A on the drive panel 20 agree with the position of the specific alignment mark M10A on the sealing panel 10 in a state that the panel 20 is facing the sealing panel 10. Then, it turns the drive panel 20 around the rotation axis J by using the θ stage to make the position of the other alignment mark M20B on the drive panel 20 agree with the position of the other alignment mark M10B on the sealing panel 10. By moving and turning the drive panel 20 only once, the drive panel 20 is aligned to the sealing panel 10 with high precision. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To make application equipment further downsized by adding a function as an input device to an active-matrix type organic EL display device in addition to a function as an output device. SOLUTION: The organic EL display device includes an array of scanning lines 2A, an array of signal lines 2B, and pixels PXL formed in a matrix, each pixel being at an intersection of each of the scanning lines and each of the signal lines. Each pixel includes a light-emitting element EL, a light-emitting circuit 21 composed of a thin-film transistor, and a light-receiving circuit 22 composed of a thin-film transistor. When the light-emitting circuit 21 is selected by the scanning line 2A, the light-emitting circuit 21 drives the light-emitting element EL according to a video signal that is inputted from the signal line 2B, thereby displaying an image on the pixels formed in the matrix. The light-receiving circuit 22 is selected in a period of time during which the light-emitting circuit does not operate, and outputs a light-receiving signal in accordance with the amount of light incident on the pixel to a different signal line 2E.

SOLUTION: A photo-resist layer 14 to which a rhodamine family coloring matter is mixed is formed in the desired pattern on an ITO(indium titanium oxide) anode 12. A hole transportation layer 16 comprising a TPD (N,N'- diphenyl-N,N'-di(3-methylphenyl)4,4'-diaminodiphenyl), a luminescent layer 18 comprising an Alq3 (tris(8-quinolinol) aluminium), and an Al cathode 20 are stacked on the ITO anode 12 and the photo-resist layer 14. Laser beams having wave length of a visible range are irradiated to the photo-resist layer 14 from the back side of a transparent glass substrate 10. The coloring matter contained in the photo-resist layer 14 absorbs the laser beams, bonding of molecules in the photo-resist layer 14 is cloven, and the photo-resist is decomposed and vaporized. At the same time, the hole transportation layer 16, the luminescent layer 18, and the Al cathode 20 are removed together. Each organic electroluminescence element is separately formed according to the desired pattern.
