Abstract

A color filter (200) comprises pixels (13) separated from each other by partitions (14) formed on a substrate (12) so as to have a plurality of color elements of ink. Dummy pixels (13′) are formed outside the area in which the pixels (13) are formed. The amount of ink applied to each of said pixels and the amount of ink applied to each of said dummy pixels are substantially equal. A protective film (21) covering said pixels (13) is formed so as to also cover said dummy pixels (13′).
