Embodiment Construction
[0036] In order to enable those skilled in the art to better understand the technical solutions of the present invention, a color filter substrate, a manufacturing method thereof, and a display panel of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0037] In order to solve the problem of light leakage at the edge of the borderless liquid crystal display panel and metal bright edges, in the disclosed technology, discontinuously distributed black matrix (BM) blocks are formed on the blank glass area of the edge of the color filter substrate to be cut, that is, a mosaic-like black matrix, This can not only ensure that the static electricity (ESD) generated during cutting cannot be introduced into the display panel through the discontinuous black matrix blocks, but also greatly improve the edge light leakage and the metal bright edge problems caused by the metal film layer on the edge of the ...

Abstract
The invention provides a color film substrate, a preparation method thereof and a display panel. The color film substrate comprises a display area and a non-display area arranged on the periphery of the display area in a surrounding mode. The color film substrate comprises a substrate body and further comprises an edge area, and the orthographic projection of the edge area on the substrate body does not exceed the orthographic projection of the non-display area on the substrate body. The edge area is provided with a shading structure, and the orthographic projection of the shading structure onthe substrate coincides with the edge area. According to the color film substrate, the shading structure is arranged in the edge area, and the orthographic projection of the shading structure on thesubstrate coincides with the edge area, so that light leakage of the edge area can be completely shielded, the phenomena of light leakage of the edge area and metal bright edges of the edge area are completely eliminated, and the user experience is improved.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to a color filter substrate, a preparation method thereof, and a display panel. Background technique [0002] In the liquid crystal display panel, during the manufacturing process of the color filter substrate, the black matrix (BM) used for shading contains carbon particles, so it has a certain conductivity. In order to avoid cutting the rear edge of the display panel formed by the color filter substrate and the array substrate The static electricity generated during the process is transmitted to the inside of the display panel through the black matrix to avoid the impact of static electricity on the inside of the display panel. Usually, the black matrix is not applied to the edge area of the color filter substrate to be cut. Generally speaking, a cutting tolerance distance is reserved between the black matrix and the edge of the color filter substrate, which cause...
