Negative photosensitive resin composition, cured film, and organic el display and manufacturing method therefor

A negative photosensitive resin composition comprising an (A) alkali-soluble resin, a (C1) photo initiator, and a (Da) black colorant,

• wherein 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,
• the one or more selected from the group consisting of the (A1-1) polyimide, the (A1-2) polyimide precursor, the (A1-3) polybenzoxazole, and the (A1-4) polybenzoxazole precursor have a structural unit having a fluorine atom at 10 to 100 mol % of all of structural units,
• the (C1) photo initiator contains an (C1-1) oxime ester-based photo initiator, and
• the (C1-1) oxime ester-based photo initiator has one or more structures selected from the group consisting of (I), (II), and (III):
• (I) one or more structures selected from the group consisting of a naphthalenecarbonyl structure, a trimethylbenzoyl structure, a thiophenecarbonyl structure, and a furancarbonyl structure;
• (II) a nitro group, a carbazole structure, and a group represented by the general formula (11);
• (III) a nitro group and one or more structures selected from the group consisting of a fluorene structure, a dibenzofuran structure, a dibenzothiophene structure, a naphthalene structure, a diphenylmethane structure, a diphenylamine structure, a diphenyl ether structure, and a diphenyl sulfide structure.
• (In the general formula (11), X7 represents a direct bond, an alkylene group having 1 to 10 carbon atoms, a cycloalkylene group having 4 to 10 carbon atoms, or an arylene group having 6 to 15 carbon atoms. In a case where X7 represents a direct bond, an alkylene group having 1 to 10 carbon atoms, or a cycloalkylene group having 4 to 10 carbon atoms, R29 represents hydrogen, an alkyl group having 1 to 10 carbon atoms, or a cycloalkyl group having 4 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, a haloalkyl group having 1 to 10 carbon atoms, a haloalkoxy group having 1 to 10 carbon atoms, an acyl group having 2 to 10 carbon atoms, or a nitro group. In a case where X7 represents an arylene group having 6 to 15 carbon atoms, R29 represents hydrogen, an alkyl group having 1 to 10 carbon atoms, a cycloalkyl group having 4 to 10 carbon atoms, an aryl group having 6 to 15 carbon atoms, a haloalkyl group having 1 to 10 carbon atoms, a haloalkoxy group having 1 to 10 carbon atoms, a heterocyclic group having 4 to 10 carbon atoms, a heterocyclic oxy group having 4 to 10 carbon atoms, an acyl group having 2 to 10 carbon atoms, or a nitro group. R30 represents hydrogen, an alkyl group having 1 to 10 carbon atoms, a cycloalkyl group having 4 to 10 carbon atoms, or an aryl group having 6 to 15 carbon atoms. a represents 0 or 1, and b represents an integer of 0 to 10.)
