Abstract
A light guide plate includes a main body, stripe structures, and light-adjusting structures. The main body includes a light-incident surface and an optical surface. The stripe structures are disposed on the optical surface. The light-adjusting structures are disposed between two adjacent stripe structures. Each of the light-adjusting structures includes a first light active surface and a second light active surface. The first light active surface faces towards the light-incident surface. The second light active surface faces towards an opposite light-incident surface. The first light active surface and the second light active surface are inclined towards different directions and formed a non-symmetrical shape. A first included angle is formed between the first light active surface and the optical surface. A second included angle is formed between the second light active surface and the optical surface. The first included angle and the second included angle are acute angles.
