The first light source is disposed on a side of a first light incident surface of the light guide plate. The first and second optical microstructures are disposed on a bottom surface of the light guide plate, and respectively located in a first and a second zone. A first light receiving surface of each first optical microstructure facing the first light source has a first edge connecting the bottom surface, and a perpendicular bisector of the first edge passes through the first light source. The first zone does not overlap the second zone. A second light receiving surface of each second optical microstructure has a second edge connecting the bottom surface, and a perpendicular bisector of the second edge does not pass through the first light source.
