Abstract

The invention provides a manufacturing method of a liquid crystal display device. In the manufacturing method, before a liquid crystal panel is treated, liquid crystals in the liquid crystal panel are turned into solid states, so that the pressure resistance of the liquid crystal panel can be greatly improved, and damage to the liquid crystal panel due to the pressure in the treatment process can be prevented. Furthermore, before the liquid crystal panel is polished, the liquid crystals therein are cooled to solid states, the solid liquid crystals achieve an effect of anchoring photoresistance columns in a closed space, and then the friction force on stress points at the top ends of panel sealants and the photoresistance columns is changed from dynamic sliding friction force into static friction force, so that the sliding resistance of the surface of the liquid crystal panel is improved, the probability of PI debris in the polishing process is reduced, and the risk of Zara can be also reduced.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing a liquid crystal display device. The manufacturing method includes but not limited to: front / rear substrate polishing method, polarizer attaching method, backlight assembly method and touch screen attaching method. Background technique [0002] Liquid crystal panels, especially TFT-LCDs, are currently the only display devices that can catch up with or even surpass CRTs in comprehensive performance such as brightness, contrast, power consumption, lifespan, volume, and weight. It has excellent performance, good mass production characteristics, high degree of automation, low cost of raw materials, and broad development space, and has become the current mainstream display product. [0003] When polishing and thinning liquid crystal panels, attaching polarizers, attaching touch screens, assembling backlights, or attaching touch screens, it is...
