Problems solved by technology
[0005] The above-mentioned method of preventing light leakage of the liquid crystal display module needs to attach more shields, which wastes a lot of manpower and material resources, but it is difficult to ensure the accuracy and consistency of the attachment, which increases the production cost and reduces the assembly cost. Efficiency, but in mass production can not completely avoid the occurrence of light leakage

A liquid crystal panel comprises a TFT substrate, a CF substrate, and a liquid crystal layer disposed between the TFT substrate and the CF substrate. The liquid crystal panel has an effective display area and an ineffective display area arranged out of the effective display area. The TFT substrate comprises an upper surface close to the CF substrate, and a lower surface far away from the CF substrate, a metal shading layer is directly made on the lower surface of the TFT substrate, and the metal shading layer is in the ineffective display area. A liquid display module having the liquid crystal panel can prevent from light leakage without other processes for light leakage prevention during assembling a lot of measures and processes for light leakage prevention can be saved, a lot of manpower and material resources can be saved, inaccuracy and inconsistency can be fundamentally avoided when an adhesive tape is adhered.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal panel and a manufacturing method thereof. Background technique [0002] With the rapid development of electronic products towards lightness, thinness and miniaturization, almost all kinds of portable electronic products use liquid crystal displays (Liquid Crystal Display, LCD) as display terminals, especially in camcorders, notebook computers, desktops, etc. Computers, smart TVs, mobile terminals, personal digital processors and other products. [0003] Liquid crystal display module is one of the key components of liquid crystal display. In recent years, with the development of technology, people put forward the requirement of no light leakage for liquid crystal display module. figure 1 It is a schematic diagram of the planar structure of the liquid crystal panel in the prior art, figure 2 for a figure 1 The schematic diagram of the cross-sectional structure...
