Abstract

The invention provides a liquid crystal display device and a backlight module thereof. The backlight module comprises a back frame, lamp sources arranged on the back frame and supporting pieces. The supporting pieces are arranged on the back frame and used for supporting a display panel arranged on bearing faces of the supporting pieces. By means of the mode, the glue-frame-free design is adopted, the production and manufacture cost of the liquid crystal display device and the backlight module thereof can be reduced, and the narrow frame design of the liquid crystal display device is facilitated.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device with frameless adhesive design and a backlight module thereof. Background technique [0002] Liquid crystal display devices generally include such as figure 1 The front frame 11, the display panel 12 and the backlight module are shown. The backlight module mainly includes a plastic frame 131, an optical film set 132, a back frame 133, a light guide plate and a light source 134, etc., wherein the plastic frame 131 and the back frame 133 Cooperate with the front frame 11 to clamp, fix and protect the display panel 12 . [0003] In the backlight module, the plastic frame 131 is generally used to support the display panel 12 and ensure the tightness of the overall structure of the backlight module. However, the manufacture of the plastic frame 131 requires not only the material cost of the plastic frame, but also the mold development c...
