Abstract: A liquid crystal optical device is comprised of a pair of substrates having respective inner major surfaces spaced apart from one another and a liquid crystal layer composed of liquid crystal molecules and interposed between the spaced inner major surfaces. An electrode layer is disposed on at least one of the inner major surfaces. An organic filter layer colored in a given color tone is electrodeposited on the electrode layer. An organic alignment layer is disposed on the filter layer in contact with the liquid crystal layer for aligning the liquid crystal molecules. An organic protective layer is interposed between the alignment layer and filter layer for adhesively securing the alignment layer to the filter layer to protect the alignment layer from stress applied thereto relative to the filter layer.

Abstract: A liquid crystal matrix type multi-color display is provided incorporating transistor structure and wherein the display electrodes are energized from the transistor drain circuit in an electroplating both to coat and color the display electrodes.

Abstract: An electrically conductive composition for electrodeposition coating comprises (A) a pigment and at least one cationic high molecular resin and (B) electrically conductive ultra-fine particles having an average particle diameter less than 0.8 .mu., the amount of (A) being 96-50% by weight and the amount of (B) being 4-50% by weight of the total solid content of the composition.

Abstract: A liquid crystal display having a multi-color display is fabricated with a plurality of display electrodes on a first substrate, on which a color filter is selectively formed by electro-depositing a polymer together with coloring matter and electroconductive particles so that the display electrodes have different colors and electroconductivity. A counter electrode is formed on a second substrate and a liquid crystal material is sandwiched between the first and second substrates, so that the material serves, in operation, as a light shutter controlled by the voltage applied between said color filter via said display electrodes and the counter electrode.

Abstract: Disclosed is a method of making a color filter for a solid state imaging device involving forming plural, spaced apart transparent electroconductive layers, insulated from one another, on a substrate and a layer of light absorbing material in the spaces between the spaced-apart layers. Co-electrodeposition of a coloring material and a polymer is used to deposit a colored layer on the electroconductive layers.

Abstract: A liquid crystal display device comprising a first display of twisted-nematic (TN) or guesthost (GH) type in front of a second LCD of TN type in which a multicolor polarizer is provided on one cell substrate. The multicolor polarizer consists of two layers and multiple picture elements. The color polarizers of one layer of the multicolor polarizer have different wavelength regions and absorption axes perpendicular to the polarizer elements of the other layer.

Abstract: A multicolor display device and its method of manufacture which comprises providing first and second spaced and opposed substrates, forming a pattern of separate groups of display electrodes on the surface of the first substrate which faces the second substrate, depositing and electrolytically oxidizing an aluminum film on each display electrode, dying the oxidized films on each separate group of display electrodes a color tone which is different from the color tones of the other display electrode groups, forming a counter electrode pattern on the surface of the second substrate, and disposing a display material in the space between the spaced apart first and second substrates.

Abstract: Multicolor filters are produced by forming a conductive thin film layer having a given pattern on a insulated substrate, and electrodepositing colored polymers on the conductive thin film layer.
