ABSTRACT:
The present invention is to provide a pigment dispersion composition for a color filter having the excellent pigment dispersing property and dispersion stability, good developing property and reactivity, and an extremely small residue generation amount after development, a production method capable of stably producing such a pigment dispersion composition, and a color filter for a display having a high transmittance and a low light scattering property. A pigment dispersion composition for a color filter containing at least a pigment, a pigment dispersing agent, a binder resin, a reactive compound, and a solvent, wherein the binder resin is a compound having a pigment adsorbing block containing a pigment adsorbing group and not containing a reactive group, and a reactive block containing a reactive group and not containing a pigment adsorbing group, is provided.
