Abstract

The invention relates to a backlight module and a liquid crystal display (LCD) adopting the backlight module. The backlight module includes a light guide plate, a reflection plate and a metal back plate for accommodating the light guide plate and the reflection plate. The metal back plate includes a bossed bottom board; the reflection plate is arranged adjacent to the bottom board; and the boss corresponds to the edge of the reflection plate and applies the acting force onto the reflection plate for the contact of the reflection plate and the light guide plate.

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 panel is a non-self-illuminating display device, in order to achieve the display purpose, it is necessary to provide a light source device for the liquid crystal panel to realize its display function, such as a backlight module, whose function is to provide the liquid crystal panel with sufficient brightness and uniform distribution. flat light. [0003] see figure 1 , is a three-dimensional exploded schematic diagram of a liquid crystal display device 1 in the prior art. The liquid crystal display device 1 includes a liquid crystal panel 19 and a backlight module 10 adjacent to the liquid crystal panel 19 . [0004] The backlight module 10 includes a light shielding tape 110 , a light source 120 , an optical film set 130 , a light guide plate 140 , a plastic frame 150 , a reflector 160 an...
