Provided is a green pigment composition which includes a halogenated zinc phthalocyanine pigment and a brominated chlorinated zinc phthalocyanine derivative having a phthalimide skeleton bonded by an alkylene group, and which enables a great enhancement in contrast without decreasing luminance and coloring power, and a color filter including the green pigment composition. The green pigment composition for color filters includes from 0.1 to 10 parts of a halogenated zinc phthalocyanine pigment derivative substituted with a functional group having a phthalimide skeleton bonded by an alkylene group per 100 parts of a halogenated zinc phthalocyanine pigment, in terms of a mass, and a color filter includes the green pigment composition for color filters.

Provided are a green pigment composition for a color filter having high brightness and wide color reproduction range in a liquid crystal display, and a color filter formed including the same. A halogenated zinc phthalocyanine containing an average of 10 to 14 halogen atoms per molecule in which an average of 8 to 12 are bromine atoms and an average of 2 to 5 are chlorine atoms is used. As a result, film thickness is less than when using Pigment Green 7 and, thus, a color filter with high brightness and wide color reproduction range can be provided.
