Abstract

A light guide plate includes an incident surface, an emitting surface adjacent to the incident surface, a bottom surface opposite to the emitting surface. At least one projection or recess is formed on the incident surface, and a multi-layer reflectivity film is formed on the projection or recess. A backlight module using the light guide plate is also provided in the present invention. The backlight module further includes at least one light source and at least one reflector coupled to the light guide plate. The light source is positioned corresponding to the projection or recess and the reflector partly surrounds the light source. The light guide plate can avoid a plurality of shadows formed adjacent to the incident surface and improve the evenness of light emitting of the backlight module.
