Backlight module and liquid crystal display

The invention relates to the field of liquid crystal display technologies. The backlight module provided by the invention sequentially comprises a printed circuit board, a first reflection plate, LED light sources, light guide plates, a diffusion plate and an optical diaphragm from the bottom up. Each light guide plate is of a rectangular structure with thin periphery and thick center, and is buckled on the corresponding LED light source via a groove at the center, and bumps are arranged on a first light reflection plane and a second light reflection plane of the light guide plate, so that mixing distance of light rays entering the light guide plate is increased, and thus the light rays are more uniformly distributed, generation of a dark space is avoided, and thin design of the liquid crystal display is facilitated; the LED light source and the light guide plate are on one-to-one correspondence, regional dimming is facilitated, and becomes more accurate during rectangular light emitting surfaces formed by the light guide plates; meanwhile, a use ratio of the light sources is further improved due to the arrangement of a third reflection plate. According to the liquid crystal display including the backlight module provided by the invention, regional dimming can be accurately achieved, and the thin design is also achieved.
