A liquid crystal display and backlight module. The backlight module comprises a base plate, first reflectors, light sources, second reflectors, diffuser plate and diffuser film. Each first reflector comprises a wave-shaped structure and is provided with a first reflecting surface facing toward the base plate and a focus. Each light source is disposed at the focus of the first reflector and the light beams from the light source reflected by the first reflector pass through the base plate toward the diffusive film in parallel. Each second reflector is disposed on the base plate and provides with a second reflecting surface faced toward the light source. Thus, mura phenomenon and interferences between the two adjacent light sources can be reduced.
