Abstract
A light guide plate () includes a light incidence surface () for receiving light beams, a light-emitting surface () for guiding light beams out of the light guide plate, and a bottom surface () reflecting and scattering light beams in directions toward the light-emitting surface. The bottom surface includes scattering-dots (), and a predetermined region of the bottom surface also includes sub-scattering-dots (). 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.
