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.
