The invention provides a coloring photosensitive composition for a color filter, the color filter, a manufacturing method thereof and a liquid crystal display device. The composition can obtain sufficient deep solidifying property on exposure for forming a coloring pattern with excellent development solubility, development latitude and pattern forming property, and realizing high contrast. The composition includes (A) a thiol compound represented by the formula (I), (B) a six-aryl-link imidazole compound, (C) a polymerism compound with alkenes unsaturated double bonds compound, (D) a dye and (E) a dye dispersant. In formula (I), A is a heterocyclic with a group that is represented by any of formula (a)-(c). In formula (a)-(c), L<1>, L<2>, L<3> represent single bond, oxygen atom, sulfur atom, -N(R<12>)-, phenylene, or linkage group combined with more than two groups independently; R<1>-R<12> represent hydrogen atom or organic group with one valence independently.
