Abstract

Disclosed herein is a light guide plate. In the light guide plate according to the present invention, a plurality of inclined regular reflecting surfaces, which is arranged in a direction perpendicular to incident light, is formed on the bottom surface of the light guide plate in the direction of the incident light.
