<p>A color filter (100) for a liquid crystal display, including an optically transparent substrate (10), a transparent conductive layer (12) formed on the substrate (10), and a colored layer (14) which is formed on the layer (12) and in which red, green, and blue picture elements are arranged in a prescribed pattern. The colored layer (14) contains at least pigments as coloring agents and transparent conductive particles having hydrophobic surface and the particles are contained in the layer (14) at a ratio of 5-50 vol.%. In addition, it is desirable that the colored layer (14) has a specific resistance of 10?-1 to 108¿ (Φ.cm). A hydrophobic compound is bonded to the surfaces of the transparent conductive particles by coupling or graft polymerization. The color filter (100) is manufactured by a process comprising, for example, the following steps (a) to (c): (a) the step of forming the transparent conductive layer having a prescribed pattern on a transparent substrate, (b) the step of preparing a micelle colloid dispersion by dispersing the pigments and the transparent conductive particles having hydrophobic surfaces in a medium containing a surface active agent having redox reactivity and an electrolyte, and (c) the step of depositing the colored layer composed of the pigments and the transparent conductive particles on the transparent conductive layer by performing electrolysis by using the transparent conductive layer as the anode.</p> |
