Abstract

Embodiments of the invention provide a negative light sensitive resin composition, a color filter and a liquid crystal display device. The negative light sensitive resin composition comprises: an alkaline soluble resin, which is a terpolymer, or a derivative of the terpolymer, made from the following three monomers: styrene, α-pinene, and a carboxylic acid or anhydride containing an unsaturated double bond; a light sensitive resin containing ethylene unsaturated double bonds, which is in a mass ratio of 0.1 to 1.2:1 to the alkaline soluble resin; a photoinitiator, which is in a mass ratio of 0.0001 to 0.001:1 to the composition; a modifying adjuvant, which is in a mass ratio of 0.001 to 0.01:1 to the solid fraction in the composition; and a solvent, which is in a mass ratio of 2 to 20:1 to the solid fraction in the composition. The color filter and the liquid crystal display device comprise a light filter structure formed by the curing of the aforementioned negative light sensitive resin composition.
