ABSTRACT:
A backlight module, suitable for supplying a plane light source. The backlight module has a light guide plate, a reflection mask and a light compensator. The light source is disposed next to a side surface of the light guide plate, such that the light generated thereby is incident on the side surface of the light guide plate, transmitted through the bottom surface, and projecting from the top surface of the light guide plate. The reflection mask is disposed next to the sidewall of the light guide plate to cover the light source. The light compensator is disposed in the reflection mask. By disposing the light compensator with multiple reflection planes in the reflection mask or forming multiple reflection surfaces of the reflection mask, the brightness at the two comers of the light guide plate near the two sides of the light source can be compensated.
