A light guide plate for distributing light from a light source includes a light scattering surface, a light output surface opposite to the light scattering surface, and a number of side surfaces surrounding the light scattering surface and the light output surface. The light scattering surface includes a number of light scattering dots thereon. The light scattering dots are arranged into a number of rows arranged from a first side of the light scattering surface to an opposite side of the light scattering surface. A distance between every two adjacent rows of the light scattering dots gradually decreases from the first side to the second side, such that the light scattering dots at the second side of the light scattering surface have a greater density than the light scattering dots at the first side of the light scattering surface.
