Provided is an organic pigment composition for color filters, which can be used preferably for a color filter that allows to produce a liquid crystal display device which has excellent heat resistance, a brighter display screen, and accordingly higher brightness; a method for producing the same; and a color filter which includes the organic pigment composition for color filters. The color filter has higher heat resistance by using the organic pigment composition for color filters which includes a phthalocyanine pigment and a pigment derivative in which the ratio of a multi-substituted phthalimide alkyl group to the whole amount of the pigment derivative is limited.

An organic pigment composition that allows a colored item to have good color saturation and high resistance to a change in hue even when subjected to a thermal history for a prolonged period. A color filter includes an organic pigment composition for color filters in a pixel portion. The organic pigment composition for color filters includes an organic pigment (A) having an average primary particle size of 100 nm or less; and a copolymer (B) of a (meth)acrylic acid ester having a phosphate group and another (meth)acrylic acid ester having no phosphate group, the amount of a nonvolatile component of the copolymer (B) being 0.1 to 15 parts relative to 100 parts of the organic pigment (A) on a mass basis.
