Abstract
A light guide plate includes a first surface, a second surface opposite the first surface, a light incident surface, and a plurality of lenticular lenses and microstructure assemblies. The light incident surface is connected with the first surface and the second surface, and light beams enter the light guide plate by the light incident surface. The lenticular lenses are disposed on the first surface. Each of the lenticular lenses is suitable to deflect imaginary light beams that are incident on the first surface in a predetermined direction to form a focus region on the second surface. The microstructure assemblies are disposed on the focus regions for guiding the light beams incident on the focus regions. A plurality of planar regions are formed on the second surface. Each of the planar regions is disposed between two adjacent microstructure assemblies and suitable for totally reflecting the light beams incident thereon.
