Abstract
The present invention is related to a backlight module and a liquid crystal display device, and includes a light source, a light guide plate, a back plate, a fixed retaining part and an elastic retaining part. The edge of the back plate is formed with a peripheral frame perpendicular to a plane of the back plate. One end of the elastic retaining part is connected to the peripheral frame, and the other end of the elastic retaining part is elastically connected to a surface of the light guide plate opposite to the light input surface. The cost of the present invention is low and the manufacture thereof is simple, while the deformation of the light guide plate due to the temperature can be transferred to a surface of the light guide plate opposite to the light input surface.
