Abstract

The invention discloses a display panel and a manufacturing method thereof and a display device. The display panel comprises a substrate, a black matrix layer and an alignment layer; the black matrix layer is arranged on the substrate and comprises a plurality of black color resistance blocks, a cross-linked polymer is distributed in each black color resistance block, and the cross-linked polymer has a first cross-linking degree, so that the black color resistance blocks are in a shading state; and the alignment layer is arranged on the side, away from the substrate, of the black matrix layer. According to the invention, light can be uniformly irradiated to form a uniform alignment layer, so that the yield of the alignment layer is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In liquid crystal display technology, liquid crystal alignment technology is one of the key technologies that determine the quality of images displayed by liquid crystal display devices. Only when the liquid crystal material in the liquid crystal display panel has a stable and uniform initial arrangement can a high-quality picture be presented. Traditional liquid crystal display devices all have a film layer for inducing the alignment of liquid crystal molecules, which is called a liquid crystal alignment layer (Alignment Layer, AL). In the preparation process, the rubbing method (Rubbing Method) is often used to arrange the liquid crystal molecules evenly. For example, the polyimide layer (Polyimide, PI) is used to mechanically rub to produce micro-grooves arranged in p...
