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