Abstract
A light guide plate including a light guide plate main body is disclosed. The light guide plate main body has a light emitting plane, a bottom plane opposite to the light emitting plane. According to a scanning mode, the light guide plate main body is divided into a plurality of subsections. Each of the opposite edges of each subsection has a borderline, and two adjacent subsections share a borderline. Furthermore, a plurality of first scattering dots disposed on the subsections of the light guide plate main body, and a plurality of second scattering dots disposed on the borderlines of the light guide plate main body.
