Beschreibung
Zusammenfassung:	An object of the invention is to provide a cured film which is high in sensitivity, capable of forming a pattern in a low-taper shape after development, capable of the change in pattern opening width between before and after thermal curing, an excellent in light-blocking property, and a negative photosensitive resin composition that forms the film. The negative photosensitive resin composition contains an (A) alkali-soluble resin, a (C1) photo initiator, and a (Da) black colorant, where the (A) alkali-soluble resin contains a (A1) first resin including one or more selected from the group consisting of a (A1-1) polyimide, a (A1-2) polyimide precursor, a (A1-3) polybenzoxazole, and a (A1-4) polybenzoxazole precursor, and has a structural unit having a fluorine atom at a specific ratio, and the (C1) photo initiator contains an (C1-1) oxime ester-based photo initiator that has a specific structure.
