Patent abstract

A liquid crystal display and a backlight module thereof are provided. A backlight module comprises a light source, a reflector, and a bottom plate. The reflector is disposed under the light source. The bottom plate is disposed under the reflector and facing a lower surface of the reflector. The bottom plate comprises a plurality of trench structures formed on a surface thereof facing the reflector. Heat-produced by the light source mixes with air in the trench structures, and the mixture of heat and air is conducted via the trench structures to the bottom plate, thereby dissipating heat.
