A problem that the invention is to provide, it is possible to obtain high contrast when used in a color filter manufacturing, and post-baked (230 ° C., 1 hour) color difference and film reduction is small, the heat resistance high pigment dispersion, and to provide a color filter having a pixel portion the pigment dispersion. The present invention includes an organic pigment having an aryloxycarbonyl group at a molecular chain terminal, and the following structural formula (a1-1): (In the formula (a1-1), k is 0 a color filter containing a polyfunctional aromatic polyesters composed of an aromatic polyhydroxy compound residue and an aromatic polyvalent carboxylic acid residue represented by a is) the average value of the recurring units of 1.5 by providing use organic pigment dispersion, to solve the above problems. .BACKGROUND
