摘要： PURPOSE:To obtain a photoconductive liquid crystal light valve (LCLV) having a light-shielding film having high impedance and light-shielding property by forming the light shielding film from a dispersion mixture of manganese oxide and silicon oxide. CONSTITUTION:The light-shielding film of LCLV 1 is a black insulating film 17a comprising manganese oxide and silicon oxide. A glass substrate in the writing side is a substrate 21a comprising a fiber optical plate. CRT 2 has a same structure as a conventional CRT except that the front surface of CRT 2 consists of a substrate 2a of a fiber optical plate. The fiber optical plates of LCLV and CRT 2 are adhered with an adhesive layer 30 comprising silicone gel, glycerine, etc. The light-shielding film 17a is a black thin film consisting of a mixture of manganese oxide and silicone dioxide in a dispersed state.

摘要： PROBLEM TO BE SOLVED: To make the water content from the outside hard to intrude and make an organic film continuos without thinning the same to thereby improve the luminous characteristic by forming an insulation layer with an inclination so that it becomes thick toward the side of edge while thin toward a central part gradually. SOLUTION: A transparent film 109 of a luminous display element is formed in a gap between picture elements of a transparent electrodes 2. A material such as SiO having an insulative characteristic is used for the film 109, which is formed by a sputtering method or the like. To form the film 109, a photosensitive polyimide being an insulative photoresist is used, then it is uniformly adhered by a spin coating method or the like and thereafter it is removed except a specified gap part by patterning. An edge of the film 109 is formed such that a required exposed part is secured on a transparent electrode 2 while the thickness becomes thin gradually toward the edge so that the edge is not formed sharply. Accordingly, a protection layer functions effectively.

摘要： PURPOSE:To obtain a photoconduction type liquid crystal light valve (LCLV) having the high resolution to permit selection of the light wavelengths to be shut off by consisting light shielding film of plural thin films respectively contg. light absorbent materials in such a manner that these light absorbent materials have light absorption spectrum distributions varying from each other. CONSTITUTION:This LCLV 1 consist of multilayered black insulating films 117 composed of plural, for example, three thin films 17a to 17c respectively contg. the light absorbent materials. The light absorbent materials of these multilayered black insulating films 117, i.e., the light shielding films have the light absorption spectrum distributions varying from each other. The writing side glass substrate of the LCVL1 is formed of a substrate 21a consisting a fiber optical plate and the front face of a CRT 2 is formed of a substrate 2a consisting a fiber optical plate. The fiber optical plates of the LCVL 1 and the CRT 2 are joined to each other via joining layers 30. The width of selection of the light wavelengths to be shut off by superposition of the light absorption spectra is expanded by combinations of the thin films 17a to 17c of the light absorbent materials.

摘要： PURPOSE:To improve resolution without forming a low-resistance material between electrode layers. CONSTITUTION:This-photoconduction type liquid crystal light valve has a pair of the electrode layers 18, 19 facing each other, a liquid crystal layer 11 and photoconductive layer 15 arranged between these electrode layers, a light reflection layer 16 on the liquid crystal layer side arranged between the liquid crystal layer and the photoconductive layer and a light absorption layer 17 on the photoconductive layer side. A protective layer 30 consisting an insulating material is formed on the light reflection layer 16 side of the light absorption layer 17. The light reflection layer 16 is formed of alternately laminated layers of TiO2 films and SiO2 films and the layer nearest the light absorption layer of the light reflection layer is formed of the SiO2. The SiO2 layer formed nearest the light absorption layer of the light reflection layer 16 consisting of the alternately laminated structure of the TiO2 films and the SiO2 films suppresses lowering of the resistance on the light reflection layer side of the light absorption layer absorption and, therefore, the resolution of the LCLV is improved.
