NEGATIVE PHOTOSENSITIVE RESIN COMPOSITION

摘要

PURPOSE: A negative photo-sensitive resin composition, a display device pattern forming method using the same, and a display device including the pattern are provided to improve resolution, permeation, heat-resistance discoloration, and adhesive. CONSTITUTION: A negative photo-sensitive resin composition includes the following: 100 parts by weight of acryl-based copolymer, polyimide-based copolymer, siloxane-based copolymer, or the copolymer of the same; 0.1-30 parts by weight of a photo-initiator; and 0.1-30 parts by weight of a photo-sensitizer represented by chemical formula 1. In chemical formula 1, the n is the integer of 1 to 10. The acryl-based copolymer is obtained by radical-polymerizing acryl monomers under an azo-initiator. The polyimide-based copolymer is obtained from diamine and dianhydride. The siloxane copolymer is obtained by hydrolyzing and condensating silane monomers under acid or base.
