A light guide plate includes a light incident surface, a light emission surface intersects with the light incident surface, and a bottom surface opposite to the light emission surface. The light incident surface includes at least a first light receiving region and at least a second light receiving region. The first light receiving region has a distinctly different structure in comparison to the second light receiving region. One end of the first light receiving region communicates with the light emission surface, and the other end of the light receiving region communicates with the bottom surface. One end of the second light receiving region communicates with the light emission surface and, the other end of light receiving region communicates with the light emission surface.
