Abstract
Disclosed is a light guide plate, comprising a light guide plate body and a plurality of micro mirrors formed on an upper surface of the light guide plate body for controlling a reflection direction of light incident on the light guide plate. The amount of light output from a backlight module using the light guide plate can be controlled by adjusting an angle of each of the micro mirrors with respect to an incident light from a light source.
