Abstract

The invention relates to a colored photosensitive resin composition,a color filter and a liquid crystal display device having the same. The colored photosensitive resin composition comprises colorant (A), alkali-soluble resin (B), photopolymerizable polymer (C), photopolymerizable initiator (D), cross-linking agent (E), and solvent (F). The hydroxyl value of the alkali-soluble resin (B) is in a range from 30-180mgKOH / g, and the cross-linking agent (E) can be expressed by the formula 1.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, and more specifically, to a colored photosensitive resin composition for color filters used in the manufacture of color filters used in color liquid crystal display devices, color filters manufactured using the same, and A liquid crystal display device including the color filter. Background technique [0002] A color filter is built into a color imaging device of a complementary metal oxide semiconductor (CMOS) or a charge coupled device (CCD) image sensor, and is actually used to obtain a color image In addition, it is widely used in imaging elements, plasma display panels (PDP), liquid crystal display devices (LCD), field emission displays (FEL), and light emitting displays (LEDs), and its application range is rapidly increasing. In particular, the use of LCDs has been increasing recently, and as a result, color filters have been recognized as one of the most important comp...
