Abstract:
1. A light guide plate comprising a plurality of light guide units, a plurality of micro structures, a light emitting surface, a bottom surface opposite to the light emitting surface, a light incident surface, and a side surface opposite to the light incident surface, the light incident surface and the side surface being connected between the light emitting surface and the bottom surface, the light guide units being disposed on the bottom surface, each of the light guide units extending along a first direction, the first direction being towards the side surface from the light incident surface, each of the light guide units comprising a plurality of geometric patterns and a plurality of stripe patterns for cascading the geometric patterns such that the geometric patterns and the stripe patterns are alternately disposed on the bottom surface and connected to each other, each of the stripe patterns in each of the light guide units being separated from each other along the first direction by one geometric pattern, the micro structures being disposed in the geometric patterns and the stripe patterns, the width of the geometric pattern along a second direction being greater than the width of the stripe pattern along the second direction, the second direction being perpendicular to the first direction, and the micro structures in the geometric patterns and the stripe patterns being arranged along the first direction.
