Abstract: A black light-shielding photosensitive resin composition, a black matrix, a black light-shielding film, a frame, and a filling material for a splicing area are provided. The black light-shielding photosensitive resin composition includes a resin (A), a pigment (B), a monomer (C), an initiator (D), and a solvent (E). The resin (A) includes an epoxy resin (A-1) and a resin (A-2) having an ethylenic unsaturated functional group. The pigment (B) includes black particles (B-1) and hollow particles (B-2).

Abstract: A white photosensitive resin composition, a white spacer, a light conversion layer, and a light-emitting device are provided. The white photosensitive resin composition includes a polymerizable compound (A), an alkali-soluble resin (B), a photopolymerization initiator (C), a solvent (D), and a white pigment (E). The polymerizable compound (A) includes an ethylenically-unsaturated monomer (A-1) represented by formula (I-1) and a thiol compound (A-2) having two or more thiol groups in one molecule, wherein based on 100 mass % of the polymerizable compound (A), a total content of the ethylenically-unsaturated monomer (A-1) and the thiol compound (A-2) is 10 mass % to 98 mass %.
