Beschreibung
Zusammenfassung:	Provided are a pigment dispersion liquid with which a cured film having low surface roughness can be formed, and a photosensitive resin composition. One aspect of a pigment dispersion liquid according to the present invention contains (A) a pigment, (B) a dispersant, (C) a sulfonic-acid-group-containing compound, and a solvent, the ratio (D90/D50) of the 90% cumulative diameter (D90) to the 50% cumulative diameter (D50) being 1.4 or less in results of measuring cumulant-analyzed volume-based particle size distribution measured by a dynamic scattering method with the (A) pigment and the (C) sulfonic-acid-group-containing compound in a particulate state. A photosensitive resin composition according to the present invention contains a pigment dispersion liquid according to the present invention.
