Abstract
The invention discloses a method for producing a liquid crystal panel. The method comprises the following steps: forming a shielding layer on the back of an array substrate and/or a color film substrate to cover a display area of the liquid crystal panel to block ultraviolet light, coating a frame sealing glue on the periphery of the array substrate and the periphery of the color film substrate and pairing a box, conducting ultraviolet-irradiation and curing on the frame sealing glue, and removing the shielding layer through a construct process, wherein the area, where the frame sealing glue is coated, is outside the shielding layer. According to the method for producing the liquid crystal panel, the shielding layer on the back of the array substrate and/or color film substrate can prevent ultraviolet from damaging liquid crystal in the liquid crystal box, therefore, the liquid crystal panel can be directly subjected to ultraviolet exposure in box pairing equipment after being coated with the frame sealing glue in the box pairing equipment to cure the liquid crystal panel, and then the liquid crystal panel does not need to be moved to separate ultraviolet exposure equipment to be exposed and cured. According to the method for producing the liquid crystal panel, the aligning accuracy of the substrate in the liquid crystal panel is improved, and the occurrence of bad phenomena like light leakage and cross color of the liquid crystal panel is reduced.
