Abstract

The invention discloses a liquid crystal display which comprises a backlight module, a liquid crystal panel, a front rail, a first stopper and a second stopper. The liquid crystal panel is arranged on the backlight module. The front rail and the backlight module are assembled to clamp the liquid crystal panel. The first stopper is arranged on the liquid crystal panel and between the liquid crystal panel and the front rail. The second stopper is arranged on the front rail and between the liquid crystal panel and the front rail. And the first and the second stoppers are suitable for contacting with each other to stop the displacement of the liquid crystal panel. As mucilage glue is not required by the first and the second stoppers, the liquid crystal display is easier to be reworked.

Description

technical field [0001] The present invention relates to a flat panel display, and in particular to a liquid crystal display. Background technique [0002] With the increasing development of the electronic industry, flat-panel displays have eliminated cathode ray tube displays and become the current mainstream. In the flat panel display, the liquid crystal display technology is the most sophisticated and popularized. [0003] figure 1 A cross-sectional view of an existing liquid crystal display, figure 2 for figure 1 Exploded view of the LCD monitor with the front frame removed. Please refer to figure 1 and figure 2 . The liquid crystal display 100 includes a backlight module 110 , a liquid crystal panel 120 and a front frame 130 . The liquid crystal panel 120 is disposed on the backlight module 110 , and the front frame 130 is assembled with the backlight module 110 to hold the liquid crystal panel 120 . In addition, in order to avoid problems such as friction or ...
