Abstract: A black positive-type photosensitive resin composition with high sensitivity is provided. The photosensitive resin composition of the invention includes (A) a binder resin, (B) a quinonediazide adduct of a phenol compound having 3 or more phenolic hydroxyl groups (hereunder also referred to as “trivalent or greater phenol compound”, and (C) a black coloring agent, wherein the quinonediazide adduct (B) includes (b1) a quinonediazide adduct wherein one of the hydroxyl groups of the phenolic hydroxyl groups of the trivalent or greater phenol compound is replaced by a structure represented by formula (I) or formula (II), and (b2) a quinonediazide adduct wherein two of the hydroxyl groups of the phenolic hydroxyl groups of the trivalent or greater phenol compound are replaced by structures represented by formula (I) or formula (II), and the total of (b1) and (b2) is at least 60 mol % of the entirety of (B). Ra to Rd and * in the formulas are as defined in the Specification.
