Black matrix structure, manufacturing method thereof, array substrate, color film substrate and display device

Abstract

The invention relates to a black matrix structure, a manufacturing method thereof, an array substrate, a color film substrate and a display device. The black matrix structure comprises first black matrixes and a plurality of preset opening areas distributed in an array mode and defined by the first black matrixes. Each preset opening area is provided with an opening area. At least one preset opening area is provided with one or more second black matrixes arranged at intervals. The edge of each second black matrix makes contact with the corresponding opening area, or makes contact with at least one edge of the corresponding first black matrix. The length of the edge, making contact with each edge of the corresponding first black matrix, of each second black matrix is smaller than the length of the edge, making contact with the corresponding second black matrix, of the first black matrix. According to the black matrix structure, the opening area is reduced, meanwhile, the probability that an observer observes black matrix graphs can be lowered, and therefore black streaks can be avoided.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a black matrix structure and preparation method, an array substrate, a color filter substrate and a display device. Background technique [0002] A pixel is the smallest display unit in a display device. Each pixel includes a plurality of sub-pixels, and color filters of different colors are respectively arranged in the plurality of sub-pixels, so that the plurality of sub-pixels display corresponding colors respectively; during the display process, by adjusting The transmittance of light in each sub-pixel, that is, the brightness of multiple sub-pixels, enables the pixel to display corresponding brightness and color. [0003] The maximum brightness displayed by the sub-pixel is related to the light transmittance of the color filter (determined by factors such as type and thickness), and the area of ​​the opening area of ​​the sub-pixel. Generally, the light trans...

[0005] But in practice, increasing the width of the black matrix 15 will easily cause the width of the black matrix 15 to be too wide, so that the viewer will observe "black streaks", especially those with a small number of pixels per unit area (low PPI) Under normal circumstances, this "black streak" defect is even more serious
