A light guide plate includes a light discharge surface, a light diffusing surface, a light incident surface, and a plurality of scattering dots. The light diffusing surface is located opposite to the light discharge surface. The light diffusing surface has a first part and a second part. The first part is adjacent to a light source. The light incident surface intersects with the light discharge surface and the light diffusing surface. The scattering dots within the first part are arranged in the form of a plurality of concentric arcs, and the scattering dots within the second part are arranged in the form of a plurality of lines.
