Abstract: 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.
