Abstract:
1. A light guide plate, including: a main body including a light incidence surface, a light-emitting surface, a light reflective surface, a first side surface and a second side surface opposite to the first side surface, wherein the light-emitting surface is opposite to the light reflective surface, the first side surface, the light incidence surface and the second side surface all are connected between the light-emitting surface and the light reflective surface, wherein the main body includes a tapered portion and a flat plate portion, the tapered portion is adjacent to the light incident surface and has an inclined surface located in the light-emitting surface and two connecting side edges respectively on a top and a bottom of the inclined surface, the connecting side edge on the top of the inclined surface is connected to a top edge of the light incidence surface, and the light-emitting surface includes a microstructure region; and a plurality of stripe microstructures distributed in the microstructure region, extended from the connecting side edge on the bottom of the inclined surface and trimmed between the light incidence surface and an opposite side of the main body, wherein a length of each of the stripe microstructures is smaller than a length of the main body.
