Problems solved by technology

This method is easy to agglomerate and produce problems such as gel
In addition, since carbon black is a conductive particle, if there is more carbon black in the photoresist system, the resistance value (Rs) of the black matrix will decrease

Embodiment Construction

[0034] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0035] The present invention firstly provides a black matrix, which is obtained by coating a mixed resin composition on a substrate and patterning it by photolithography after drying, wherein the mixed resin composition includes an adhesive resin (Polymer) , a photoinitiator (Photo Initiator), a small molecule monomer (Monomer), a solvent (Solvent), a light-shielding material, an azo compound, and an additive, and the azo compound has polarizing properties. The adhesive resin can form a film layer and support cross-linking reaction, the photoinitiator can quickly form free radicals under light, the small molecule monomer can polymerize functional groups, and the solvent can adjust coating performance. The light-shielding material can play a li...

Abstract

The invention provides a black matrix, a manufacture method of the black matrix and a liquid crystal panel with the black matrix. The black matrix is obtained in a manner that mixed resin composite is coated on a substrate, and patterning is carried out by photolithography after the mixed resin composite is dried, wherein the mixed resin composite comprises adhesive resin, photoinitiator, a micromolecule monomer, solvent, shading materials, azo-compound and additive. According to the black matrix, the azo-compound with a polarization characteristic is added to improve the shading performance, improve the optical density value of the black matrix, reduce the use amount of the shading materials in the black matrix and increase the resistance value of the black matrix.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a black matrix, a manufacturing method thereof and a liquid crystal panel with the black matrix. Background technique [0002] A liquid crystal display (LCD, Liquid Crystal Display) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or laptop screen, etc. [0003] Generally, a liquid crystal display device includes a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. Among them, the structure of the liquid crystal display panel is mainly composed of a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), a color filter substrate (Color Filter, CF), and a liquid crystal layer ( Liquid Crystal Layer), its working principle is to con...
