Abstract

The invention is related to the backlight module, and the liquid crystal display device. The backlight module includes a light guide plate and a frame. In order to house the light guide plate, the frame includes a first sidewall containing an aperture for the light guide plate to enter into the frame. The aperture is in use for the light guide plate to enter into the frame so as to prevent the frame from distortion caused by extrusion. The backlight module is easy of assembling.

Description

【Technical field】 [0001] The invention relates to a backlight module and a liquid crystal display device. 【Background technique】 [0002] Since the liquid crystal in the liquid crystal display panel itself does not have light-emitting characteristics, in order to achieve the display effect, it is necessary to provide the liquid crystal display panel with a light source device, such as a backlight module, whose function is to supply the liquid crystal display panel with a plane with sufficient brightness and uniform distribution. Light. [0003] figure 1 It is a schematic explosion diagram of a liquid crystal display device in the prior art. The backlight module 10 includes a light guide plate 14 and a plastic frame 16 . [0004] The light guide plate 14 includes a light incident surface 144 , a light exit surface 145 adjacent to the light incident surface 144 , a bottom surface 146 opposite to the light exit surface 145 , and two opposite sides 141 , 142 adjacent to the l...
