Method for producing liquid crystal panel

Abstract

A method for preparing a liquid crystal panel, comprising: forming a shielding layer (11) which covers a display area (21) of the liquid crystal panel on a back surface of an array substrate (1) and / or a colour film substrate (2), so as to block ultraviolet light; coating a sealant around the array substrate (1) and the colour film substrate (2) and aligning the substrates, wherein the area coated with the sealant is located outside the shielding layer (11); performing ultraviolet irradiation on the sealant to cure same; and removing the shielding layer (11) via an etching process. By means of the preparation method, the shielding layer on the back surface of the array substrate (1) and / or the colour film substrate (2) can prevent ultraviolet light from damaging liquid crystals in a liquid crystal box. Therefore, ultraviolet exposure can be directly performed on the liquid crystal panel in an alignment device after the sealant coats the alignment device, so that the liquid crystal panel is cured. Therefore, the preparation method for the liquid crystal panel improves the alignment accuracy of the substrates in the liquid crystal panel, and reduces undesirable phenomena such as light leakage, cross colour and so on of the liquid crystal panel.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a method for preparing a liquid crystal panel. Background technique [0002] The liquid crystal panel mainly includes: a color filter substrate connected to the cell, an array substrate, and a liquid crystal molecular layer located between the color filter substrate and the array substrate. [0003] Under the prior art, the preparation method of the liquid crystal panel is as follows: coating the sealant on the color filter substrate or the array substrate, and injecting liquid crystal molecules into the color filter substrate and the array substrate, and then putting the color filter substrate, the array substrate and the The liquid crystal molecular layer between the substrate and the array substrate is put into the box alignment equipment to form a liquid crystal panel, and then the liquid crystal panel is taken out, and put into the ultraviolet curing equipment for ultraviol...
