ABSTRACT:
A color filter comprises a substrate and colored resin films, disposed on the support, including a blue resin film containing blue colorant particles dispersed therein, a green resin film containing green colorant particles dispersed therein and a red resin film containing red colorant particles dispersed therein. Scattering characteristic from the respective colored resin films is uniformized by satisfying the following conditions. The average particle volume V.sub.B, V.sub.G and V.sub.R of the blue, green and red colorants, respectively, are set to satisfy V.sub.B <V.sub.G <V.sub.R. The surface roughness of or the colorant content in the colored resin films is set to successively increase in the order of the blue resin film, the green resin film and the red resin film.
