The light guide plate has a first light emitting surface, a second light emitting surface, and a light incident surface. The light source faces the light incident surface. The first light transmissive substrate is located on the first light emitting surface. The second light transmissive substrate is located on the surface of the first light transmissive substrate facing away from the light guide plate, and the thickness of the second light transmissive substrate is smaller than that of the first light transmissive substrate. The printing ink layer is located on the surface of the second light transmissive substrate facing the first light transmissive substrate, and on an edge of the second light transmissive substrate.
