Abstract
A color filter comprising a transparent substrate, more than one transparent, electrically conductive circuit provided on a surface of the transparent substrate, window-shaped, colored coating films on the more than one transparent, electrically conductive circuit, and frame-shaped light-screening coating films interlaced between the window-shaped, colored coating films, the frame-shaped light-screening coating films having a larger film thickness than the window-shaped, colored coating films, which is free from the leakage of light from around each of the colored coating films so that it provides high contrast image and its method of manufacture.
