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 in a first irradiation amount through a mask having a predetermined pattern of a certain light transmittance and at least once displacing the mask to another position on the photosensitive coating film and exposing the photosensitive coating film to light in a second irradiation amount different from the first irradiation amount through the mask; (B) developing and removing a photosensitive coating film portion exposed to light in one of smallest and largest irradiation amounts 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 in sequence of difference in irradiation amounts to form different colored layers, respectively; and (Z) transcribing the colored layers, the transparent electrically conductive layer and the alignment film onto another substrate.
