Abstract: A light guide plate is disclosed. The light guide plate includes a light guide plate substrate including a light inlet surface and a light outlet surface, where a first groove is disposed on the light guide plate substrate, and is configured to accommodate a light emitting portion of a first light source, and a bottom surface of the first groove forms the light inlet surface. The light guide plate also includes a light reflection layer, disposed on a part of an outer surface of the light guide plate substrate except the light inlet surface and the light outlet surface, where light emitted from the first light source enters the light guide plate substrate through the light inlet surface, and is refracted by the light reflection layer, so that the light emitted from the first light source comes out through the light outlet surface.
