Method for producing color filter

A method for producing a color filter comprising the steps of:

• (A) forming a photosensitive coating film on a transparent electrically conductive layer formed on a surface of a transparent substrate and exposing said 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 a pattern selected from the group consisting of a pattern having the smallest degree of light transmittance and a pattern having the largest degree of light transmittance for exposing said 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 being repeated for the respective patterns having different degrees of light transmittances in one sequence selected from the group consisting of increasing light transmittance and decreasing light transmittance to form different colored layers, respectively;
• and
• (C) selectively forming a metal layer on at least one exposed region of said transparent electrically conductive layer.
