Abstract

The invention provides a liquid crystal display panel. The liquid crystal display panel comprises an array substrate and a color film substrate, wherein the array substrate comprises a first glass substrate, a scanning line, a data line, an organic insulating layer and a pixel electrode located on the organic insulating layer, the color film substrate comprises a second glass substrate, black matrixes located on the second glass substrate, a plurality of color layers located between the adjacent black matrixes and flat layers covering the black matrixes and the color layers, the color layers comprise a red color layer, a green color layer and a blue color layer, the organic insulating layer is formed by exposing a halftone photomask, the height of the organic insulating layer in an area corresponding to the red color layer is H1, the height of the organic insulating layer in an area corresponding to the green color layer is H2, the height of the organic insulating layer in an area corresponding to the blue color layer is H3, and H2 is more than H1 and less than H3. According to the invention, the organic insulating layers with inconsistent heights are formed through exposure of thehalftone photomask, so that different box thicknesses of areas corresponding to different color layers are adjusted, and the purpose of adjusting the chromaticity of the panel is achieved.

Description

technical field [0001] The invention relates to the technical field of panel display, in particular to a liquid crystal display panel. Background technique [0002] figure 1 It is a structural schematic diagram of a liquid crystal display panel. The liquid crystal display panel includes an array substrate 10 and a color filter substrate 20 arranged oppositely. The color filter substrate 20 includes a black matrix 22 on a glass substrate 21 and a color layer between adjacent black matrices 22. 23 and the transparent electrode 24 covered on the black matrix 22 and the color layer 23, the color layers 23 are red color layer, green color layer and blue color layer respectively. Both the array substrate 10 and the color filter substrate 20 are provided with red pixel units (red), green pixel units (green) and blue pixel units (blue) that are oppositely arranged. For the film thickness of the color layer of the color filter substrate, the film thickness of the red color layer<...
