Abstract

The related backlight module comprises: a light guide plate, a light source group included a source and a near reflection cover, and a metal frame. Besides, this invention also includes a grounding elastic piece set between the cover and frame. This invention can ensure grounding effect.

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-luminescent display device, in order to achieve the display effect, it is necessary to provide a surface light source device for the liquid crystal display to realize the display function, such as a backlight module, whose function is to provide a surface light source with sufficient brightness and uniform distribution to the liquid crystal display. [0003] A prior art backlight module 100 such as figure 1 As shown, the backlight module 100 includes a light guide plate 110 , a light source group 114 , a reflector 115 and a metal frame 116 . [0004] 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 opposite to the light exit surface 112 . The light source gro...
