Disclosed is a pigment dispersion composition for black matrix excellent in light shielding property, excellent in taper angle, large in developing margin, high in adhesion, and excellent in edge linearity, and a pigment dispersion resist composition for black matrix containing the same . In order to solve the above problems, the pigment dispersion composition for black matrix of the present invention is a pigment dispersion composition for black matrix containing carbon black, silica, pigment dispersant containing basic group, pigment derivative, acid group-containing resin and solvent, 1 to 7 parts by mass of silica having a primary particle size of 20 to 60 nm and an average primary particle size of 1 to 20 nm based on 100 parts by mass of carbon black. |
