PROBLEM TO BE SOLVED: To provide a thin film color filter which is improved in adhesive strength with an electrode substrate and is excellent in process-proofness and durability. SOLUTION: This color filter is produced by immersing the substrate having a transparent electrically conductive film into dispersion liquid in which the micelle formation of pigments having the spectroscopic characteristics of three primary colors proceeds in an aqueous medium by using a surfactant which has electrochemically oxidizable and/or reducible parts and subjecting the substrate to the energizing treatment in such a manner that the temperature of the dispersion liquid is set to be 5-20 deg.C. The substrate having the transparent electrically conductive thin film is plastic film substrate.
