    摘要: A method for producing a color filter involves (A) forming a photosensitive coating film on at least a transparent electrically conductive layer formed on an outermost surface of a transparent substrate and exposing the photosensitive coating film through a mask having patterns of at least three different degrees of light transmittances; (B) developing and removing a photosensitive coating film region corresponding to one of the patterns of the smallest and largest degrees of light transmittances for exposing the transparent electrically conductive layer and electrodepositing a colored coating on the exposed transparent electrically conductive layer for forming a colored layer thereon. Operation of developing and removing the photosensitive coating film and electrodepositing the colored coating is repeated for the respective patterns of different degrees of light transmittances in sequence of difference in light transmittances to form different colored layers. The electrodepositing is in turn performed at each time in a decreasing voltage.
