Abstract

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.

Description

technical field [0001] The present invention relates to a colored photosensitive composition for color filters used in liquid crystal display elements (LCD) and solid-state imaging elements (CCD, CMOS, etc.), color filters formed using the composition, methods for producing the same, and liquid crystals Display components. This patent application claims the priority of Japanese Patent Application No. 2007-054642 filed on March 5, 2007 and Japanese Patent Application No. 2008-007392 filed on January 16, 2008. Background technique [0002] Conventionally, as a method for forming a pattern of a colored photosensitive composition, there is a photolithography method in which a colored photosensitive composition is applied to the entire surface of a substrate, dried, and then partially and selectively irradiated with active energy rays such as ultraviolet rays. For curing, only the uncured part is removed by development to form a pattern, and a colored photosensitive composition ...
