Display panel and display device

Abstract

The invention discloses a display panel which comprises an array substrate and an opposite substrate which are oppositely arranged, the array substrate comprises a plurality of pixel units arranged inan array mode, each pixel unit comprises a plurality of sub-pixel units, and a black matrix is arranged on the side, facing the array substrate, of the opposite substrate. A black matrix layer comprises at least one pixel opening, a blocking area and at least one communication opening, the pixel openings are in one-to-one correspondence with the sub-pixel units, the blocking area divides the pixel openings, the communication openings are formed in the blocking area, and the pixel openings are communicated with one another through the communication openings. According to the display panel, through the arrangement of the communicating openings, the mutual communication of all the pixel openings can be realized, so the blocking effect of the terrain of the black matrix layer can be overcome,an alignment liquid can cross the blocking effect of the blocking area and quickly and uniformly flow into the openings of other pixel areas, and the problem of non-sticking of the alignment liquid is solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device including the display panel. Background technique [0002] The role of the alignment film in the liquid crystal panel is very important. It not only controls the quality of the liquid crystal alignment, but also has a great influence on the reliability of the liquid crystal panel. Moreover, the coating condition of the alignment film will affect the optical taste of the entire panel, and ultimately affect the customer's satisfaction. viewing experience. [0003] Such as figure 1 As shown, a general liquid crystal display panel includes an array substrate 10 and a color filter substrate 20 disposed opposite to each other. Wherein, the array substrate 10 includes a first base substrate 11, a TFT layer 12 disposed on the side of the first base substrate 11 facing the color filter substrate 20, and a TFT layer 12 disposed on the side of...

AI Technical Summary

Problems solved by technology

The nozzle pitch of existing alignment film coating machines cannot ensure that alignment liquid drops into each pixel opening

Due to the blocking effect of the topography of the black matrix layer, the alignment liquid cannot pass through the barrier area, resulting in no alignment liquid in some pixel openings, which will eventually cause the problem of non-sticking of the alignment liquid in this area, resulting in bright spots
