Abstract

Provided is a colored photo-sensitive composition having a high sensitivity and a good developablity, even if the ratio of content of a pigment, relative to the total solids of the colored photo-sensitive composition, is 20% by mass or more. The colored photo-sensitive composition includes (A) a resin which is increased, by action of an acid, in solubility into an alkali developing solution; (B) a pigment; (C) a compound which produces an acid upon irradiated by active light or radial ray; and (D) a solvent, wherein the ratio of content of the (B) pigment, relative to the total solids of the colored photo-sensitive composition, is 20% by mass or more.
