The dispersibility of the pigment after a period of time is good, and a photosensitive resin composition capable of forming fine patterns with low exposure doses and high resolution can be provided with a pigment dispersion liquid that can be applied even after a period of time, and a method for manufacturing a photosensitive resin composition using the pigment dispersion liquid. The pigment dispersion liquid related to the present invention contains a pigment, a solvent, and a compound represented by formula (1). In the formula, R1 and R2 independently represent a hydrogen atom or an organic group, but at least one of them represents an organic group. R1 and R2 may form a cyclic structure by bonding, and may include a bond of a hetero atom. R3 represents a single bond or an organic group. R4 to R9 independently represent a hydrogen atom, an organic group, etc., but R6 and R7 do not become hydroxy groups. R10 represents a hydrogen atom or an organic group.
