Negative photosensitive resin composition

Abstract

[Problem] To provide a photosensitive resin composition that can produce a hardened film with high visible light shielding even with reduced amounts of colorants such as carbon black. [Solution] A negative photosensitive resin composition containing the following components (A) to (C). (A) A phenolic varnish-type phenolic resin, wherein the molar ratio of structural units derived from cresol (a1), dihydroxynaphthalene (a2), benzaldehyde (a3), and salicylaldehyde (a4) [(a1):(a2):(a3):(a4)] is 1:0.25~4.0:0.25~4.0:0.25~4.0 / (B) Photosensitive agent / (C) Organic solvent. none
