A light guide plate ( 300 ) includes a light incidence surface ( 310 ) for receiving light beams, a light-emitting surface ( 320 ) for guiding light beams out of the light guide plate, and a bottom surface ( 330 ) reflecting and scattering light beams in directions toward the light-emitting surface. The bottom surface includes scattering-dots ( 341 ), and a predetermined region of the bottom surface also includes sub-scattering-dots ( 342 ). At least one sub-scattering-dot is disposed around each scattering-dot. The sub-scattering-dots are smaller than the scattering-dots. With this micro-configuration, intensities of light beams output from the light guide plate are uniform and bright.
