Abstract
A light guide plate, a backlight module and a display device are provided. The light guide plate includes a main body and optical structures. The main body has a light-incident surface, an opposite light-incident surface, and an optical surface. The optical structures are disposed on the optical surface. Each of the optical structures has a first optical active surface and a second optical active surface, and the first optical active surface and the second optical active surface are inclined towards different directions and formed in a non-symmetrical shape. A first inclined angle is formed between the first optical active surface and the optical surface. A second inclined angle is formed between the second optical active surface and the optical surface. The first included angle is greater than the second included angle, and a light-emitting angle of the light guide plate decreases exponentially with the first inclined angle.
