Abstract

A light guide plate includes a main body, first stripe structures and second stripe structures. The main body has an optical surface, a light-incident surface and an opposite light-incident surface. The main body has a hole passing through the optical surface, and the optical surface has a first region and a second region which are separated by an imaginary line. The imaginary line intersects the hole. The hole has a first side near the opposite light-incident surface and a second side near the light-incident surface. A portion of each of the first stripe structures is disposed in the first region. The second stripe structures are disposed in the second region. An extending direction of at least one portion of each first stripe structure is vertical to the light-incident surface, and a portion of the second stripe structures extends to the first side of the hole near the opposite light-incident surface.
