Problems solved by technology

[0006] However, the existing design of the correction alignment mark has the following defects: On the one hand, in actual production, the raised part rubs against the surface of the substrate for a long time, which will cause the correction alignment mark to be deformed, so that the coating machine cannot Identify this mark; on the other hand, the external dimension of the correction alignment mark is relatively small, generally about 0.7mm, so designing it as a raised structure will make it easy to fall off

Abstract

The invention provides an alignment board and relates to the technical field of display in one embodiment. The alignment board is capable of preventing frictional deformation or dropping of a compensating alignment marker on the alignment board. The alignment board comprises a substrate layer and a resin layer covering the substrate layer, wherein the substrate layer is exposed from the substrate layer in a predetermined region; in the predetermined region, a groove is formed in the substrate layer to form the compensating alignment marker of the alignment board; the substrate layer surrounding the groove is exposed; the substrate layer is made of a stretching-resistant material, while the resin layer is made of a stretchable material. The alignment board is used for manufacturing a display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an alignment plate. Background technique [0002] Liquid crystal display is currently the most widely used display device. It is mainly composed of two parts: a liquid crystal panel and a backlight module. Among them, the liquid crystal panel includes an array substrate and a color filter substrate formed in a box, and a liquid crystal layer filled in between. [0003] In the manufacturing process of the liquid crystal panel, in order to arrange the liquid crystal molecules according to a certain orientation, an alignment layer needs to be formed on the inner surface of the substrate. At present, the alignment layer is generally produced by a roller transfer printing method, which mainly transfers the alignment liquid to the alignment plate through the roller, and then transfers the alignment liquid to the surface of the substrate through the alignment plate. [0004] In actual...
