Abstract

The invention discloses a backlight module, and liquid crystal display device of using the backlight module. The backlight module includes a light guide plate, a light source near to the light guide plate, and a frame for accommodating the light guide plate and light source. The light guide plate includes at least a notch located at edge. The frame includes a bottom border with a stopper being setup. Being accommodated inside the notch, the stopper bunts the light guide plate. The backlight module plays function for protecting the light source.

Description

【Technical field】 [0001] The invention relates to a backlight module and a liquid crystal display device using the backlight module. 【Background technique】 [0002] Since the liquid crystal display is a non-self-illuminating display device, in order to achieve the display effect, it is necessary to provide a light source device for the liquid crystal display to realize the display function, such as a backlight module, whose function is to provide a backlight with sufficient brightness and uniform distribution to the liquid crystal display source. [0003] A backlight module 100 of the prior art is shown in FIG. 1. The backlight module 100 includes a light guide plate 110, a light source group 114, a reflector 115 and a light guide plate 110, a light source group 114, The frame 116 of the reflection plate 115 . The light guide plate 110 includes a light incident surface 111 , a light exit surface 112 intersecting the light incident surface 111 , and a bottom surface 113 opp...
