Pigment dispersion composition for black matrix, resist composition for black matrix, and black matrix

Provided is a pigment dispersion composition for a black matrix, from which a black matrix having excellent adhesion to a substrate can be formed. The pigment dispersion composition for a black matrix includes a black colorant, a sulfonated product of copper phthalocyanine, and at least one amine compound selected from the following compounds (A)-(D): (A) an amine compound having a pyridine skeleton; (B) an amine compound having an aniline skeleton; (C) an amine compound having a carbazole skeleton; and (D) an amine compound having a linear alkyl group having 8 or more carbon atoms and having a total number of 20 or less carbon atoms. 本发明提供一种黑矩阵用颜料分散组合物，由其能够形成相对于基板的密合性优异的黑矩阵。该黑矩阵用颜料分散组合物包含黑色着色剂、酞菁铜的磺化物和胺化合物，所述胺化合物是选自下列化合物(A)～(D)中的至少一种：(A)具有吡啶骨架的胺化合物；(B)具有苯胺骨架的胺化合物；(C)具有咔唑骨架的胺化合物；(D)具有碳原子数为8以上的直链烷基、碳原子总数为20以下的胺化合物。
