Abstract

The invention discloses a display panel, a manufacturing method thereof, and a display device. The display panel includes a display area and a non-display area surrounding the display area; the display panel further includes a first substrate, a first deformation layer and a first alignment layer; wherein, the first deformation layer is arranged on the first substrate and is used to generate reversible deformation, And the first deformation layer is located at least on the side of the non-display area close to the display area; the first alignment layer is disposed on the first substrate and the first deformation layer. The present invention can improve the diffusivity of the material of the first alignment layer, thereby improving the film formation uniformity of the first alignment layer, and improving the display effect of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device having the display panel. Background technique [0002] In the liquid crystal display technology, the liquid crystal alignment technology is one of the key technologies for determining the quality of the images displayed by the liquid crystal display device. 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. Conventional liquid crystal display devices all have a film layer for inducing alignment of liquid crystal molecules, which is called a liquid crystal alignment layer (Alignment Layer, AL). In the preparation process, the rubbing method is often used to make the liquid crystal molecules evenly arranged. For example, a polyimide layer (PI) is mechanically rubbed to generate parallel mi...
