Abstract

The invention discloses a colored photosensitive resin composition. The colored photosensitive resin composition comprises: coloring agent (A), alkaline soluble resin (B), photo-polymerizing compound (C), photo-initiator (D),solvent (E) and additive agent (F), wherein the photo-initiator (D) is a compound represented by the chemical formula (1), and the additive agent (F) is a compound represented by the chemical formula (3), wherein, in the chemical formula (1), R1 is represented by the chemical formula (2), R2 is C1-C8 alkyl group, substituted phenyl group or unsubstituted phenyl group, or substituted benzyl group or unsubstituted benzyl group, R3 is substituted diphenyl sulfide group or unsubstituted diphenyl sulfide group, and in the chemical formula (2), R4 is C1-C4 alkyl group, and R5 is C3-C8 alicyclic alkyl group or aromatic alkyl group, and in the chemical formula (3), n is an integer from 1 to 12, the chemical formula (2) -R4-R5.

Description

[0001] This application claims the rights of Korean Patent Application No. 10-2013-0094691 filed on August 9, 2013, which is hereby incorporated into this application by reference in its entirety. Technical field [0002] The present invention relates to a colored photosensitive resin composition, a color filter including the colored photosensitive resin composition, and a liquid crystal display including the colored photosensitive resin composition. Background technique [0003] The color filter can be built into an image sensor, such as a complementary metal oxide semiconductor (CMOS) or a charge coupled device (CCD) color image recording instrument, and it can actually be used to obtain a color image. In addition, its application range has rapidly expanded to include image sensor elements, plasma display panels (PDP), liquid crystal displays (LCD), field emission displays (FEL), and light emitting displays (LED). [0004] Specifically, recently, the use of LCDs has been further e...
