Abstract

The invention provides a display substrate and a display device, and aims to solve the problems of deflection and disorder of liquid crystals and light leakage at a position where a friction groove is not formed under the influence of a spacer in the conventional display unit. The display substrate comprises a substrate, and black matrixes, spacers and a friction film layer, which are formed on the substrate, wherein the black matrixes comprise a plurality of first black matrixes which are arranged along a first direction and a plurality of second black matrixes which are arranged along a second direction; the area of one first black matrix between two adjacent black matrixes along the second direction is smaller than a threshold valve; the threshold value is a product of the distance between two adjacent second black matrixes along the second direction and the maximum width of one first black matrix between two adjacent second black matrixes; the spacers are positioned at positions corresponding to the black matrixes, and the shadows of the spacers along a friction direction are projected onto the first black matrixes.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] At present, a liquid crystal display device includes a color filter substrate and an array substrate in a box, wherein spacers are generally arranged on the color filter substrate to support the two substrates and form a space for filling liquid crystals. [0003] Such as figure 1 As shown, the color filter substrate generally includes: a transparent substrate 1 , a black matrix 2 , a color film layer 3 , a protective film layer 4 , a spacer 5 , and a PI film 6 covering the spacer 5 and the protective film layer 4 . Among them, such as figure 2 As shown, the black matrix 2 crosses horizontally and vertically to form a plurality of display units, and the color film layer 3 is located at the positions of the display units. The PI film is formed by forming a PI (Polyimide, polyimide) film on the surface of ...
