Abstract: A light guide plate includes a first light emitting surface and a second light emitting surface. The first light emitting surface and the second light emitting surface are connected by an inclined surface. The first light emitting surface is connected to the light incident surface of the light guide plate and is higher than the second light emitting surface, and the inclined surface is provided with a protruding structure. According to the technical solutions in the embodiments of the present disclosure, part of the light projected onto the inclined surface is reflected back to the light guide plate by the protruding structure and reflected back and forth between the bottom surface of the light guide plate and the inclined surface to be sufficiently mixed and homogenized. A part of the homogenized light emits from the second light emitting surface to compensate for a longitudinal brightness difference. Another part of the homogenized light exits from the protruding structure on the inclined surface and the first light emitting surface, thereby reducing the transverse brightness difference. Thus, the poor user experience such as dazzling can be reduced and the viewing effect can be improved.
