Title:
NEGATIVE PHOTOSENSITIVE RESIN COMPOSITION, PARTITION WALL, BLACK MATRIX AND OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2013/031736
Kind Code:
A1
Abstract:
Provided are: a negative photosensitive resin composition, which contains a pigment at high concentration and is capable of producing a black matrix that has high light shielding properties, which has high re-solubility, which is capable of providing a coating film by a slit coating method, said coating film being free from defects, and which has such a viscosity that enables coating by a slit coating method; a partition wall which is formed by curing the photosensitive resin composition and has high light shielding properties; and an optical element which has the partition wall. A negative photosensitive resin composition, which contains an alkali-soluble resin, a photopolymerization initiator, a black coloring agent and a solvent, and wherein the black coloring agent is contained in an amount of more than 20% by mass relative to the total solid content of the composition and the solvent contains a compound represented by R1O(C2H4O)2R2 (wherein R1 represents a methyl group and R2 represents an alkyl group having 2 or 3 carbon atoms) in an amount of 20-100% by mass relative to the total mass of the solvent; and a partition wall which is formed of a cured film of the negative photosensitive resin composition and which is formed to have such a shape that divides the surface of a substrate into a plurality of compartments for pixel formation.
