Abstract

The invention provides an alignment substrate and a manufacturing method thereof. The alignment substrate is provided with a display area and a non-display area surrounding the display area; the alignment substrate includes a base substrate, a rectification layer, and an alignment film layer; the rectification layer includes a plurality of rectification blocks, and each rectification block is A sharp corner is provided on the side facing the display area, all the rectifying blocks are arranged apart from each other, a flow guide groove is formed between the rectifying blocks, and the edge of the rectifying layer is flush on the side away from the display area; The alignment film layer is disposed on the base substrate, disposed in the display area and extended in the guide groove of the non-display area. The invention helps realize narrow frame and increases display ratio.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an alignment substrate and a manufacturing method thereof. Background technique [0002] One of the development trends of liquid crystal display (TFT-LCD) is narrow frame display, reducing non-display area to increase display ratio. [0003] In the existing alignment film coating process, due to the tension effect on the surface of polyimide (PI), the material of the alignment film, it is difficult to expand the polyimide solution, resulting in a jagged convex-concave structure on the edge of the formed alignment film, that is, the alignment film The edges are uneven, and the width of the jagged convex-concave structure is about 700 microns to 800 microns. In order to ensure that the alignment film pattern covers the entire effective display area, the actual alignment film pattern needs to be expanded to a certain size, and the edge of the alignment film needs to be expanded, w...
