Abstract

The invention provides a method for manufacturing a liquid crystal panel. The method comprises: two mother boards are provided; the two mother boards are jointed with each other; the two jointed mother boards are irradiated by laser; and the area irradiated by laser is cooled by a refrigerant which contains supercritical fluid. The invention also provides a method for cutting a base plate.

Description

technical field [0001] The invention relates to a liquid crystal panel manufacturing method and a substrate cutting method. Background technique [0002] Liquid crystal display devices are widely used in modern information equipment, such as monitors, televisions, mobile phones, and digital products, due to their advantages of light weight, low power consumption, low radiation, and easy portability. [0003] A liquid crystal display device usually includes a liquid crystal panel and a backlight module stacked, wherein the liquid crystal panel includes a thin film transistor array substrate and a color filter substrate oppositely arranged, and a sandwiched between the two substrates liquid crystal layer. In order to increase production and reduce costs, in the production process, a plurality of thin film transistor array units are usually fabricated on one mother substrate, and a plurality of color filter units are fabricated on another mother substrate; and the above two mo...
