Abstract

The invention provides a liquid crystal display device and a backlight module thereof. The backlight module comprises a light guide panel, an optical film, a binding part and fixing columns; the optical film is fixed onto the light guide panel through the binding part, a first positioning hole is formed in the light guide panel, a second positioning hole is formed in the optical film, the first positioning hole and the second positioning hole are oppositely arranged, and the inner wall of each of the first positioning hole and the second positioning hole is connected with side walls of the fixing columns. The invention further provides the liquid crystal display device. By the arrangement, displacement of the optical film on the horizontal and vertical directions can be prevented by the backlight module, folding of the optical film can be prevented comprehensively, and optical performance of the liquid crystal display device is ensured to be unaffected by displacement of the optical film.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a backlight module thereof. Background technique [0002] The backlight module is one of the key components in the liquid crystal display device, which is used to provide a uniform and sufficient light source for the liquid crystal display panel, so that the liquid crystal display device can display images normally. The optical film on the backlight module can be used to diffuse the light of the light source to make the light uniform, and the optical film can also cover the dots on the light guide plate of the backlight module to protect the prism sheet of the backlight module and avoid mirror scratches role. [0003] figure 1 It is a schematic cross-sectional view of a traditional backlight module. The light guide plate 100 and the optical film 200 on the backlight module 10 are stacked and fixed with a glue frame 300 . The o...
