BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY DEVICE USING SAME

摘要

The present invention provides a backlight module and a liquid crystal display device using the backlight module. The backlight module includes: a backplane (2), a backlight source (4) arranged in the backplane (2), a light guide plate (6) arranged in the backplane (2), and a reflector plate (8) arranged between the backplane (2) and the light guide plate (6). The backplane (2) includes a bottom plate (22) and a plurality of side plates (24) perpendicularly connected to the bottom plate (22). The bottom plate (22) has a surface that faces the light guide plate (6) and is an arc curved surface (222). The reflector plate (8) is positioned on the arc curved surface (222) and shows an arc curved configuration. The light guide plate (6) is supported on opposite ends of the reflector plate (8) to effectively reduce the thickness of the backlight module and not to be in complete contact with the reflector plate to thereby effectively prevent the occurrence of abrasion and wear of the light guide plate resulting from insufficient smoothness of the bottom plate of the backplane and effectively extend the lifespan of the backlight module.
