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. The substrate having the colored layer thereon is cut to produce plural color members.
