Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] refer to Figure 7 , the color filter of the embodiment of the present invention may include:

[0024] Substrate 1;

[0025] A compensation layer 4 formed on the substrate 1, the thickness of the compensation layer 4 gradually decreases from the center of the substrate to the edge of the substrate;

[0026] A black matrix 2 formed on the compensation layer 4;

[0027] The color filter layer 3 formed in the pixel area defined by the black matrix 2 may include a red filter layer, a green filter layer and a blue filter layer.

[0028] Wherein, the compensation layer is transparent and can be made of plastic or inorganic polymer material. The prefabricated compensation layer can be pasted on the substrate, or the compensation layer can be for...

Abstract

The invention provides a color filter, a liquid crystal display panel and a display device, and belongs to the field of liquid crystal display. The color filter comprises a substrate, a compensation layer formed on the substrate, black matrixes formed on the compensation layer, and color filtering layers formed in pixel areas which are defined by the black matrixes, wherein the thickness of the compensation layer is gradually reduced from the center of the substrate to edges of the substrate. The uniformity of the film thickness of the color filtering layers can be improved.

Description

technical field [0001] The invention belongs to the field of liquid crystal display, in particular to a color filter, a liquid crystal display panel and a display device. Background technique [0002] A liquid crystal display panel is formed by an array substrate and a pair of color filters. Each layer of the color filter is made by spin-coating a polymer solution on a glass substrate to form a film, and then patterning it. refer to Figure 1~4 , the production process of the color filter is: step S11, providing a substrate 1, and spin-coating a layer of photoresist material 21 for black matrix on the substrate; 21 After exposure and development, the pattern of the black matrix 2 is formed; step S13, spin-coat a layer of colored photoresist 31 on the substrate 1 that has completed step S12, and use a patterned mask to process the colored photoresist 31 After exposure and development, the pattern of the color filter layer 3 is formed. [0003] Since the linear velocity at ...
