Abstract: A planar lighting device includes a light guide plate and a side-emitting lighting module. The light guide plate includes a light emission surface, a back light surface, and at least one side surface. The back light surface is opposite to the light emission surface, and the side surface extends between the light emission surface and the back light surface. The side-emitting lighting module is embedded into the light guide plate, such that the side-emitting lighting module emits light toward the side surface of the light guide plate. The light is then guided by the light guide plate and emerges from the light emission surface of the light guide plate.
