NEGATIVE PHOTOSENSITIVE RESIN COMPOSITION, PARTITION WALL, BLACK MATRIX, COLOR FILTER, AND LIQUID CRYSTAL DISPLAY ELEMENT

WIPO Patent Application WO/2012/176816

A1

Provided are: a negative photosensitive resin composition that allows the formation of a partition wall (black matrix) having a fine line pattern and microscopic contact holes; a color filter that can be produced by low power consumption and bright black-matrix-on-array type liquid crystal display elements; and a liquid crystal display element. The negative photosensitive resin composition contains: a photopolymerization initiator (C1) comprising an alkali-soluble resin having an acidic group and an ethylenic double bond, a black colorant, and an O-acyl oxime compound having a carbazole skeleton; and a photopolymerization initiator (C2) comprising an O-acyl oxime compound having a 4-(phenylthio)benzoyl group. In the negative photosensitive resin composition and partition wall obtained using the negative photosensitive resin composition, the ratio of the total content of the photopolymerization initiator C1 and the photopolymerization initiator C2 with respect to the total solid content is 3.5 to 7.0 mass%, and the ratio of the photopolymerization initiator C1 with respect to said total content is 5 to 15 mass%.
