Abstract

The present application provides a display panel and a manufacturing method thereof. The display panel includes a substrate; a pixel electrode layer located on the substrate; an alignment layer located on the pixel electrode layer; and a pixel electrode layer located on the pixel electrode layer. and the adsorption layer between the alignment layer. In the present application, an adsorption layer is formed before forming the alignment layer, so that the alignment layer can be uniformly diffused on the pixel electrode layer regardless of the topography, thereby eliminating oblique mura and improving product yield.

Description

technical field [0001] The present application relates to the field of display panel manufacturing, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In the liquid crystal display panel industry, the alignment film PI (polyimide) is used to align the liquid crystal, so that the liquid crystal has a certain pre-tilt angle in the no-voltage state, and plays an important role in inducing and controlling the normal operation of the liquid crystal. [0003] The alignment film is generally formed on the upper and lower substrates after the upper and lower substrates are manufactured and before the liquid crystal is poured into the ODF. Since the existing alignment film is usually formed by inkjet printing, there are many contact hole areas on the upper and lower substrates, and PI droplets cannot be uniformly formed in the contact hole area, resulting in twill mura in this area, which reduces the quality of the product. yield.
