PROBLEM TO BE SOLVED: To provide light emitting devices (52, 80, 110, 128, and 130) which have a light emitting region (66) formed on a plate and is suitable for a flat panel anode-ray tube display. SOLUTION: The light emitting region has a plurality of light emitting particles (72). A part of the respective outer surface of the light emitting particles is covered in equal angles by a kind or more of coatings (74, 82, 84, 112, and 114). These coatings provide various kinds of light reflection, gettering, promotion of strength, and contrast promotion functions. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide light emitting elements in which no cross talk is caused and light emission is conducted by a very low driving voltage in an atmospheric pressure environment and to provide a field emission display having the elements. SOLUTION: When a pulse voltage is applied to a driving electrode 4, electric field is concentrated in the vicinity of a slit and an electric field discharging phenomenon is generated. Discharged electrons hit a stimulable phosphor layer 8 through an electrically conductive coating layer 6 and an electron passing layer 7 by applying a bias voltage to a transparent electrode 9. Thus, the layer 8 is stimulated and light emission indicated by arrow marks is generated through the electrode 9. By arranging a light emitting element 1 in a two dimensional manner, a field emission display is constituted. COPYRIGHT: (C)2004,JPO
Abstract:
PURPOSE:To improve the luminous efficacy by making the thickness of a coat composed of metal oxide thicker in the circumferential inner side of a bulb disposed along the circumferential direction than the outer side thereof. CONSTITUTION:The film thickness of a coat 10 of metal oxide is formed in such a manner that the film thickness t1 of the part situated in the outside of glass bulbs 5a, 5b, 5c is thinner than the film thickness t2 of the part situated in the inside, or t1
Abstract:
PURPOSE:To extend the lifes of the normal luminous body and phoshor without the passing of the excitation wire lost by covering the piotective film on the fluorescent material applied to the inside of the radiation tube.

PROBLEM TO BE SOLVED: To provide an active matrix type organic electroluminescent element having a high resolution/high aperture ratio with improved manufacturing yield. SOLUTION: A first substrate 110 and a second substrate 130 in which a pixel comprising red, green, and blue sub-pixels is defined are disposed so as to contact each other. The organic electroluminescent element comprises array elements 112 including a plurality of switching devices formed by a sub-pixel unit on the first substrate, a color changing part 136 on a bottom of the second substrate, having red, green, blue color changing layers, 132a, 132b, 132c, for changing blue color light into three primary colors of red, green and blue, a first electrode 140 on a bottom of the color changing part made of a conductive material having permeability, an organic electroluminescent layer 144 on a bottom of the first electrode having a blue color emitting layer, a second electrode 146 patternized by sub-pixel unit on a bottom of the organic electroluminescnet layer, and an electric connector 148 formed on a location where the switching element and the second electrode are corresponding for electrically connecting the switching element and the second electrode.

Abstract:
PROBLEM TO BE SOLVED: To provide an organic EL panel having high quality. SOLUTION: A glass substrate 30 and a protective material 40 for protecting an organic EL element 12 are formed by a glass material to form the organic EL panel 50 having excellent resistance to changes of temperature. Moreover, the protective material 40 and the glass substrate 30 are formed by a glass material to reduce thickness of the organic EL panel more than a case where a metallic can is used. Furthermore, a degree of freedom in selection of adhesive for bonding both of them mutually is markedly increased when compared with the case where the metallic can is used. COPYRIGHT: (C)2003,JPO
