Abstract
A color filter is formed on one surface of one of a pair of light-transmitting substrates and an organic overcoat film for smoothing is formed on the color filter. In addition, a metallic or silicon nitride film such as SiNx and a metallic or silicon oxide film such as SiOx are formed thereon in this order before forming the ITC film. The formation of the metallic or silicon nitride film and the metallic or silicon oxide film enhances the adhesion of the ITC film.
