Abstract
A method of manufacturing a color filter for a multicolor liquid crystal display unit comprises the steps of forming an organic high-polymer color filter layer over a surface of a substrate. A protective film is then formed on the color filter layer and on the surface of the substrate. Thereafter, a thin metal electroless plating film is formed on the protective film. The electroless plating film is then patterned to form a shading film.
