The light guide plate includes a light-emitting surface, a bottom surface, a light-incident surface, plural stripe microstructures and plural light-guiding microstructures. The bottom surface is opposite to the light-emitting surface. The light-incident surface is connected between the light-emitting surface and the bottom surface. Light emitted by the light source enters the light guide plate from the light-incident surface. The stripe microstructures are disposed on the at least one of the light-emitting surface and the bottom surface, and each of the stripe microstructures has two opposing side surfaces and an active surface. The side surfaces are respectively connected to two opposite sides of the active surface. The light guide plate has a thickness direction. Each of the side surfaces is inclined towards the active surface, and there is an included angle is form
