Abstract
A light guide plate includes: a light emitting surface; a bottom surface opposite to the light emitting surface; a light incident surface perpendicularly connected with the light emitting surface; a first side surface perpendicularly connected with both the light incident surface and the light emitting surface; a second side surface opposite to the first side surface; two protrusions outwardly extending from the first side surface; and two protrusions outwardly extending from the second side surface. A thickness of each protrusion of the first side surface decreases with increasing distance away from the light incident surface, and a thickness of each protrusion of the second side surface also decreases with increasing distance away from the light incident surface.
