Zusammenfassung:The invention relates to a light guide plate comprising a incident surface, wherein the incident surface is provided with at least one circular arc-shaped structure and a plurality of V-shaped grooves along the circular arc-shaped surface of the circular arc-shaped structure; the V-shaped grooves in the light guide plate are formed by cutting through the rotating around the central shaft by utilizing a cutter; the processing technology is simple and rapid; the shape of the produced grooves has good repeatability; and the grooves in the circular arc-shaped structure make the light rays emitted by a light emitting diode be effectively scattered when entering the light guide plate so as to eliminate the bright and dark areas of the light emitting from the light guide plate and the phenomena of uneven light emitting of horoscopic bright rays and the like.
