Micro-structure points are provided and distributed randomly and densely on the first plate surface. Among multiple side surfaces of the light guide plate body, at least one side surface is provided with a plurality of first teeth arranged sequentially in parallel. The first teeth extend along a height direction of the light guide plate body. A first groove is arranged between every two neighboring first teeth. The light incident surface is formed by the plurality of first teeth and the plurality of first grooves.
