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, wherein the alignment substrate comprises a substrate, a rectification layer and an alignment film layer; the rectification layer comprises a plurality of rectification blocks; a sharp corner is arranged on one side, facing the display area, of each rectification block, all the rectification blocks are arranged in a separated mode, flow guide grooves are formed between the rectification blocks, and the edges of the sides, deviating from the display area, of the rectification layer are flush with one another; the alignment film layer is arranged on the substrate, arranged in the display area and arranged in the flow guide groove of the non-display area in an extending mode. According to the invention, a narrow frame can be realized, and the display scale is increased.

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...
