Abstract

An object of the present invention is to provide a colored photosensitive resin composition capable of forming a color filter having a higher brightness than that of the color filter formed from the conventionally known colored photosensitive resin composition. The colored photosensitive resin composition according to the present invention comprises a colorant, a resin, a polymerizable compound, and a polymerization initiator, the colorant comprising a compound represented by formula (1) and an α-type and/or β-type copper phthalocyanine pigment, wherein Mrepresents an r-valent metal ion; k represents the sum of the number of —SOand the number of —SO—N—SO—Rin the compound represented by formula (1); r represents an integer of 1 or more; Rrepresents a fluoroalkyl group having 1 to 12 carbon atoms; and the compound represented by formula (1) has at least one —SOor —SO—N—SO—R.
