Abstract
A light guide plate with multi-directional structures includes a main body, a plurality of first microstructures and a plurality of second microstructures. The main body includes a light-incident surface, a light-emitting surface and a reflecting surface. The light-incident surface connects the light-emitting surface and the reflecting surface. The first microstructures are disposed on the light-emitting surface or the reflecting surface and arranged along a first extending direction. The second microstructures are disposed on the light-emitting surface or the reflecting surface and arranged along a second extending direction. The second microstructures and the first microstructures are disposed on the same plane and intersect with each other. Each of the second microstructures is a single stripe pattern, and has a width which becomes gradually smaller from one end of the second microstructure near the light-incident surface to the other end of the second microstructure away from the light-incident surface.
