Abstract:
A light guide plate (10) of a preferred embodiment includes: an incident surface (12) for receiving incident light beams from a corresponding light source; an emitting surface (16); and a bottom surface (11) opposite to the emitting surface. The bottom surface defines a plurality of V-shaped grooves. A side (17) of each V-shaped groove is a curved surface, and at least one part of the curved surface is wave-shaped. The light guide plate can improve the utilization of light beams, reduce wastage of light beams and configure the uniformity of luminance.
