Abstract: The disclosure provides a backlight module and a liquid crystal display device. The backlight module, including a rear cover, a light guide plate, and an LED lamp assembly, the rear cover including an accommodation space in which the light guide plate is located, and the LED lamp assembly being located between a sidewall of the rear cover and a light entrance end face of the light guide plate, wherein a keep-space protrusion is arranged on the sidewall of the rear cover adjacent to the LED lamp assembly, and a screw hole configured to be threaded to a bezel is arranged on the keep-space protrusion.

Abstract: Disclosed are an edge type backlight module and a display device. The edge type backlight module includes a light guide plate, a plurality of light sources, and dim area compensating units disposed between two adjacent light sources. Light rays of each light source enter the light guide plate from a lateral side, and by the effect of the light guide plate, light rays go out of the light guide plate from the front face. The dim area compensating units are used for providing light compensation for the dim areas between two light sources. By setting the dim area compensating unit between two light sources, the utility model of the present disclosure discloses an edge type backlight module which solves the dim area effect effectively, thus avoiding defects of the prior art for solving the dim area effect.
