Embodiment Construction

[0029] In order for those skilled in the art to better understand the technical solution of the present invention, the color filter substrate, display panel and display device of the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0030] In the prior art, since the array substrate and the color filter substrate are prone to alignment errors, color mixing and light leakage at side viewing angles generally occur in display devices. For high-resolution liquid crystal display products and high color gamut LTPS (low temperature polysilicon) products, the possibility of color mixing and light leakage at side viewing angles is greater.

[0031] In order to solve this problem, the inventor found that black matrix light-shielding protrusions can be made in the area where the black matrix is ​​located between adjacent color filter units or the thickness of the black matrix can be increased to prevent color mixing betw...

Abstract

The invention belongs to the field of display technology, in particular to a color film substrate, a manufacturing method thereof, a display panel and a display device. The color film substrate comprises a substrate and a color filter layer arranged on the substrate. The color filter layer comprises color fitter units which are of at least two colors and distributed in an array. A black matrix is between adjacent color fitter units. A flat layer is arranged on the color filter layer. Grooves corresponding to black matrixes are arranged on the flat layer. Light-blocking layers are arranged in the grooves. Due to the light-blocking layers, mix-color light is blocked so that one color can be observed at the lateral angle so that color mixture and light leakage are solved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a color filter substrate and a manufacturing method thereof, a display panel and a display device. Background technique [0002] The liquid crystal panel is an important part of the liquid crystal display. During production, the array substrate and the color filter substrate are manufactured first, and the color filter substrate and the array substrate are boxed together through a cell alignment process to form a liquid crystal panel. The box-fitting process includes: dripping liquid crystal on one of the array substrate or color filter substrate through the ODF (OneDrop Filling) process, coating the sealant on the other substrate of the array substrate or color filter substrate, and placing the array substrate Carry out box alignment with the color filter substrate, and cure the sealant to form a liquid crystal panel. [0003] During the process of box alignment, ...
