ABSTRACT OF THE DISCLOSURE: A method for producing a color filter involves (A) forming a photosensitive coating film on a transparent electrically conductive layer provided on an outermost surface of a substrate having an alignment film, and exposing the photosensitive coating film to light through a mask having patterns of at least three different degrees of light transmittances; (B) developing and removing a photosensitive coating film portion registering with one of the patterns of smallest and largest degrees of light transmittances for exposing the transparent electrically conductive layer and electrodepositing a colored coating on the exposed electrically conductive layer for forming a colored layer thereon, operation of developing and removing the photosensitive coating film and electrodepositing the colored coating being repeated for the respective patterns of different degrees of light transmittances in sequence of difference in light transmittances to form different colored layers, respectively; and (Z) transcribing the colored layers, the transparent electrically conductive layer and the alignment film onto another substrate.
