  • Patent number: 4999094
    Abstract: A method for manufacturing a color member, e.g., a color filter for a display device. A conductive thin film layer having given plural patterns is formed on an electrically insulative substrate. On the conductive thin film layer, a colored layer is formed by electrodepositing a coloring material and polymer on the conductive layer.

  • Patent number: 4787716
    Abstract: A colored article, e.g., a multicolored filter for a display device, comprises a first electroconductive layer with a low resistance formed on a substrate. A second electroconductive layer resistant to electrolytic corrosion and comprised, e.g., of SnO.sub.2, Sb.sub.2 O.sub.3, ZnO, CdO, Ga.sub.2 O.sub.3, Au, Ag, Ni, Al and Si, is formed directly on the first layer. A color layer is formed on the second layer by electrodeposition to impart a desired color tone to the article.

  • Patent number: 4779957
    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.

  • Patent number: 4639088
    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.

  • Patent number: 4617094
    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.
