Color film substrate, manufacturing method thereof, and display device

Abstract

The present invention relates to a color film substrate, a manufacturing method thereof, and a display device. The color film substrate comprises m columns of list-structured sub-pixels and n columns of island-structured sub-pixels, wherein m>=1, and n>=1; a first black matrix is disposed between the adjacent rows of the list-structured sub-pixels, and the list-structured sub-pixels cover the first black matrixes; a second black matrix is disposed between the adjacent rows of the island-structured sub-pixels; main spacers are arranged on the list-structured sub-pixels on the first black matrixes; and the auxiliary spacers are arranged on the second black matrixes. According to the technical scheme, the main spacer and the auxiliary spacer having the same height can be formed through the same equipment or technology, due to the fact that the base of the main spacer is higher than the base of the auxiliary spacer, an upper surface of the main spacer is higher than an upper surface of the auxiliary spacer, so that the technology of manufacturing the main spacer and the auxiliary spacer is simplified when the height difference between the upper surfaces of the main spacer and the auxiliary spacer is ensured.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a color filter substrate, a manufacturing method of the color filter substrate, and a display device. Background technique [0002] In the design of liquid crystal display devices, in order to ensure the process requirements of the liquid crystal edge and the good pressure resistance of the panel, it is usually necessary to design a main spacer and a sub-spacer between the upper and lower substrates, and there is a spacer between the main and sub-spacers A certain height difference. [0003] There are two types of pixel arrangement structures in traditional color filter substrates, one is a strip structure, such as figure 1 As shown, the other is an island structure, such as figure 2 shown. When spacers are formed in the above two structures, in order to form a height difference between the main spacer and the auxiliary spacer, it is necessary to use devices of diff...

AI Technical Summary

Problems solved by technology

When spacers are formed in the above two structures, in order to form a height difference between the main spacer and the auxiliary spacer, it is necessary to use devices of different specifications to form the main spacer and the auxiliary spacer respectively, Or it can be realized by adjusting the half-mask exposure process, which is complex and difficult to control
