(Problem) When the color filter is used, high contrast can be exhibited, and the surface roughness can be suppressed or prevented even after treatment in the molding process of the color filter, post bake, UV cleaning, or the like, thereby achieving good display performance. In addition, it provides a pigment dispersion composition showing a high dispersion stability. (Solution means) A pigment dispersion composition containing organic pigment fine particles and a polymer compound having a pigment adsorber, wherein the organic pigment fine particles are compatible with the organic pigment solution in which an organic pigment is dissolved in a good solvent and the good solvent. The pigment dispersion composition which is build-up pigment microparticles | fine-particles which mixed and precipitated the poor solvent used as a poor solvent about an organic pigment. |
