NEGATIVE PHOTOSENSITIVE RESIN COMPOSITION, CURED FILM, ELEMENT PROVIDED WITH CURED FILM, DISPLAY DEVICE PROVIDED WITH ELEMENT, AND ORGANIC EL DISPLAY
The present invention provides a negative photosensitive resin composition that has high pigment dispersibility and stability and can reduce residues of unexposed portions during development. The present invention provides a negative photosensitive resin composition containing an (A) alkali-soluble resin, a (B) dispersant having an amine value exceeding 0, a (C) benzofuranone based organic pigment having an amide structure, a (D) radical polymerizable compound, and a (E) photoinitiator. In this negative photosensitive resin composition, the (A) alkali-soluble resin contains one or more selected from the group consisting of a (A1) polyimide, a (A2) polyimide precursor, a (A3) polybenzoxazole, and a (A4) polybenzoxazole precursor, and the (B) dispersant having an amine value exceeding 0 contains a (B1) dispersant including a repeating unit represented by general formula (2) and a repeating unit represented by general formula (3) and a (B2) dispersant that is an acrylic block copolymer having an amine value of 15 to 60 mgKOH/g and/or a (B3) dispersant having a urethane bond.

(In general formula (2), R.sup.1 represents an alkylene group. R.sup.2 and R.sup.3, which may be the same or different, each represents hydrogen, an alkyl group or a hydroxyl group. x represents an integer of 0 to 20. However, when x is 0, at least one of R.sup.2 and R.sup.3 is an alkyl group. m represents an integer of 1 to 100. In general formula (3), n represents an integer of 1 to 100.)
