RADIATION SENSITIVE COMPOSITION FOR BLUE COLOR FILTER, COLOR FILTER AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

The present invention relates to a radiation-sensitive composition for a blue color filter, comprising: (A) a colorant including a blue coloring agent; (B) an alkali soluble resin; (C) a multifunctional monomer; (D) a photopolymerization initiator including one or more types selected from the group consisting of a compound represented by chemical formula 3, an oxime ester-based compound and a biimidazole-based compoun; (E) an antioxidant including one or more types selected from the group consisting of a phenol-based antioxidant, a phosphorus-based antioxidant and a sulfur-based antioxidant, wherein the total sum amount of component (E) is 1 to 100 parts by weight based on 100 parts by weight of the total sum of component (D). In the chemical formula 3, each sign is as defined in the detailed specification. Accordingly, the radiation-sensitive composition for a blue color filter capable of forming an excellent blue pixel with high luminance is provided by widely selecting the photopolymerization initiator.
