A color filter layer for a color liquid crystal display device is provided, including a plurality of color filters each formed on delineated stripes of transparent electrodes formed substantially parallel to each other on a transparent insulating substrate. These color filters are each electrochemically formed on the delineated stripes of transparent electrodes serf-aligned to the delineated stripes. In addition, a layer of transparent resin material is further provided as a leveling layer that is cured by being exposed to light incident from the backside of the substrate using the color filters as a mask and fills gap portions between the color filters.
