Abstract

The invention provides a making method and device for a display substrate. The method includes the steps that whole-surface coating is carried out on a pre-arranged substrate through a full-coating APR transfer plate loaded with alignment liquid, and an alignment film layer located on the pre-arranged substrate is formed, wherein the pre-arranged substrate comprises multiple display areas distributed in a row and list spaced mode, and the area between every two adjacent display areas is a non-display area; the alignment film layer is covered with a shielding layer, wherein the shielding layer comprises multiple shielding areas and multiple non-shielding areas, the shielding areas correspond to the display areas, and the non-shielding areas correspond to the non-display areas; the alignment film layer covered with the shielding layer is treated, so that the portions, corresponding to the non-shielding areas, of the alignment film layer are removed, the portions, corresponding to the shielding areas, of the alignment film layer are retained, and thus corresponding alignment films are formed on the surfaces of the display areas corresponding to the shielding areas. By means of the method, different products can share one full-coating APR transfer plate, so that cost is reduced, and productivity is improved.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a method and device for manufacturing a display substrate. Background technique

[0002] The specific steps of forming a liquid crystal display box are as follows: first, apply a sealant around one glass substrate, and then add liquid crystals to the center of another glass substrate by dropping method. The two glass substrates are vacuum bonded, and finally the frame sealing glue is cured to complete the box forming process. In the production process of liquid crystal display panels, in order to make the liquid crystal molecules align normally, it is necessary to coat a layer of polyimide film on the surface of the array substrate and color filter substrate, and then perform a rubbing process on the polyimide film to ensure Realize the alignment of liquid crystal molecules. Therefore, the polyimide film coating of the array substrate and the color filter substrate is a very i...
