Abstract

The invention provides a photosensitive resin composite and application thereof. The photosensitive resin composite contains alkali soluble resin (A), a compound having ethylene unsaturated bases (B), a photoinitiator (C), a solvent (D), black pigment (E) and a thermal initiator (F). The photosensitive resin composite for a black matrix in the invention has advantages of improving resolution and a taper angle.

Description

technical field [0001] The invention provides a photosensitive resin composition for a black matrix and a color filter and a liquid crystal display element formed by using the black matrix, in particular, a photosensitive resin composition for a black matrix with improved resolution and taper angle Objects and color filters and liquid crystal display elements formed using the black matrix. Background technique [0002] In recent years, various liquid crystal display technologies have developed vigorously. In order to improve the contrast and display quality of current liquid crystal displays, black Matrix, the black matrix can prevent problems such as a decrease in contrast and a decrease in color purity caused by light leakage between pixels. In the past, the materials used in the black matrix are mainly evaporated films containing chromium or chromium oxide. However, when the above-mentioned evaporated films are used as the material of the black matrix, there are disadvan...
