Abstract

The invention relates to a backlight module group and a liquid crystal display device adopting the backlight module group. The backlight module group comprises a light guide plate and a frame holding the light guide plate. The light guide plate comprises an elastic member extending outward along the side of the light guide plate. The frame comprises a slot correspondingly clipping the elastic member, and the slot penetrates the frame. In the process of assembling and disassembling the backlight module group and the liquid crystal display device, the frame is uneasy to be damaged.

Description

technical field [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module.
