Light guide plate with multi-directional structures

A light guide plate with multi-directional structures, the light guide plate comprising:

• a main body, comprising:
• a light-incident surface;
• a light-emitting surface;
• and
• a reflecting surface opposite to the light-emitting surface, wherein the light-incident surface connects the light-emitting surface and the reflecting surface;
• a plurality of first microstructures disposed on the light-emitting surface or the reflecting surface, wherein the first microstructures are arranged along a first extending direction from a first side of the main body to an opposite second side of the main body;
• a plurality of second microstructures disposed on the light-emitting surface or the reflecting surface, wherein the second microstructures are arranged along a second extending direction from a third side of the main body to an opposite fourth side of the main body, wherein the second microstructures and the first microstructures are disposed on the same plane and intersect with each other, wherein each of the microstructures is intercepted by each of the second microstructures and each of the second microstructures is in a single stripe pattern and has a width which becomes gradually smaller from one end of each of the second microstructures near the light-incident surface to the other end of each of the second microstructures away from the light-incident surface, so that lengths of the first microstructures are increasing from the first side of the main body near the light-incident surface to the opposite second side of the main body away from the light-incident surface.
