The present invention provides a pigment dispersion and a colorant composition in which a pigment is finely dispersed and has excellent dispersion stability, and further provides a color filter having excellent surface roughness and contrast of a pixel coating film. A pigment dispersion comprising at least a pigment, a low-molecular pigment dispersant represented by the following general formula (1), and a high-molecular pigment dispersant having a basic group in its structure. P- (NHCO-XY) n (1) [Where P is a pigment residue, X is an aryl group, n is an integer of 1 to 4, Y is a carboxyl group, an ester group, a hydroxyl group, a mercapto group, an amino group, a sulfonic acid group, and the following general formula: It is selected from the groups represented by (2). — (CH 2 ) m —NR 1 R 2 (2) (Here, R 1 and R 2 may be the same or different and are selected from hydrogen, an alkyl group, and an aryl group, and m represents an integer of 1 to 6.)] [Selection diagram] None |
