Problems solved by technology

However, although the colored photosensitive resin composition that has been used is widely recognized as having high-sensitivity characteristics, when a pixel is formed under the condition of a low exposure amount, there is a disadvantage that surface defects such as development spots occur.

[0137] Figure 1a-Figure 1c is a schematic diagram of a process for manufacturing a color filter using a colored photosensitive resin composition according to the first embodiment of the present invention.

[0138] The present invention is to coat the colored photosensitive resin composition involved in the present invention on the substrate, such as Figure 1a As shown, a colored layer ( 11 ) made of a colored photosensitive resin composition is formed on the upper portion of the substrate ( 10 ). For this process, for example, a colored photosensitive resin composition diluted with a solvent is applied to the upper part of the substrate by a coating method such as rotation, slitting and rotation, slitting, flattening, spraying, and inkjet, and the solvent, etc. are volatilized. Sexual components are volatile. In this way, the colored layer (11) made of the colored photosensitive resin composition is formed, and the formed colored layer is composed of solid components of th...

Abstract

The present invention relates to a coloring light-sensitive resin composition, and a colorful optical filter and a liquid crystal display device manufactured by using the coloring light-sensitive resin composition. The coloring light-sensitive resin composition includes (A) a colorant, (B) an alkaline soluble resin, (C) a light polymerized compound, (D) a light polymerization initiator, (E) a solvent and (F) a fluorine series reactivity additive represented by a chemical formula 1. Furthermore, when being manufactured the colorful optical filter, the coloring light-sensitive resin composition is capable of keeping high contact angle and a low surface energy, and showing characteristics of non spot and good transparence after developing, such that the composition can be nicely adapted to the colorful optical filter and the liquid crystal display device. In the chemical formula 1, R1 is independently selected from ethylene, (iso)propone, butane, (poly)ethylene glycol and (poly)propone ethandiol, R2 is hydrogen or methyl, Rf is fluorine series polyatomic alcohol represented by a chemical formula 2; in the chemical formula 2, R3 is methano or (poly)ethylene glycol symmetrical to two sides of R4, R4 is carbon or CF2O-(CF2CF2O)a - (CF2O) b -OCF2, a and b are separately selected from integers which are more than 0 or 1, a sum of a and b is an integer from 1 to 20, R5 is independently selected from hydrogen, methyl, ethyl group, propyl, butyl or CD2-O-CH2-CPF2P+1, P is an integer from 1 to 10, n is an integer from 1 to 20.

Description

technical field [0001] The invention relates to a colored photosensitive resin composition, and a color filter and a liquid crystal display device manufactured by using the composition. Background technique [0002] The color filter (color filter) is installed in the color photography device of image sensors such as complementary metal oxide semiconductor (CMOS), charge coupled device (CCD), and can actually be applied in color imaging Among them, it is widely used in photographic elements, plasmas, plasma display panels (PDP), liquid crystal displays (LCD), free electron lasers (FEL), light emitting diodes, etc., and its application range is rapidly expanding. Especially recently, with the expansion of the application range of LCD, the color filter is considered to be one of the most important components in the imaging of LCD. [0003] The color filter is produced by forming a desired color pattern using a colored photosensitive resin composition containing a colorant. Sp...
