摘要： A color filter for a liquid crystal display device comprises an optically transparent substrate, a transparent conductive layer formed on the substrate, and a color layer formed on the transparent conductive layer with red, green and blue pixels arranged in a predetermined pattern. The color layer comprises pigments for coloring purpose and transparent conductive particles having a hydrophobic surface. The transparent conductive particles are included from 5% to 50% by volume of the color layer. The color layer may preferably have a specific resistivity of from 10.sup.-1 .OMEGA..multidot.cm to 10.sup.8 .OMEGA..multidot.cm. The transparent conductive particles comprise base transparent conductive particles having a hydrophobic compound bound on their surface by coupling or graft polymerization. A typical process of the color filter production comprises the steps of: (a) forming the transparent conductive layer of a predetermined pattern on the transparent substrate, (b) preparing a micelle colloid dispersion by dispersing a pigment and transparent conductive particles having hydrophobic surface in a medium containing a redox reactive surfactant and an electrolyte, and (c) carrying out an electrolysis in the micelle colloid dispersion by utilizing the transparent conductive layer on the transparent substrate for the anode to deposit the color layer comprising the pigment and the transparent conductive particles on the transparent conductive layer.

摘要： A color filter formed in accordance with the invention is formed by depositing a thin film of organic pigment an on electrode by electrochemical methods. An organic pigment is included in an aqueous micellar solution that includes a surfactant that has redox reactivity. The surfactant preferably has a metallocene such as ferrocene at the hydrophobic terminal end group. A transparent substrate having a transparent electrode thereon is emersed in the micellar solution. Voltage is applied to the transparent electrode and the organic pigment will form on the transparent electrode. Conductive particles, polymer material or conductive polymer material can be included with or on the pigment. Alternatively, the polymer or conductive polymer can be layered.
