Abstract
A backlight module is disclosed, comprising a light guide plate and light sources, where the light guide plate comprises lateral incident faces, an exit face that joins the lateral incident faces, and an underside that corresponds to the exit face. The light sources each comprises an emitting surface, is disposed near one side of one lateral incident face of the light guide plate, and corresponds to the lateral incident face of the light guide plate with the emitting surface. The backlight module further comprises diffusion strips, where the diffusion strips each is disposed in between one lateral incident face of the light guide plate and the emitting surface of the light source, and the light rays emitted from the emitting surface of the light source pass the diffusion strip and diffuse into the light guide plate. This invention further discloses a liquid crystal display.
