Claim:
1. A light guide plate, comprising a light exit surface, a reflection surface opposite to the light exit surface, and at least one light incidence surface connecting to the light exit surface and the reflection surface, wherein the reflection surface comprises a plurality of first minute projection structures and a plurality of second minute projection structures projecting toward interior of the light guide plate, the light guide plate further comprising two side surfaces connecting to the light exit surface, the reflection surface, and the at least one light incidence surface, the second minute projection structures being arranged between the first minute projection structures and the two side faces of the light guide plate, wherein the first minute projection structures each comprise at least two side faces coated with a high reflectivity material and the at least two high reflectivity material coated side faces of the first minute projection structure define at least one included angle pointing toward the at least one light incidence surface; and the second minute projection structures each comprise a side face that is coated with a high reflectivity material and the side face of the second minute projection structure defines two angles, which are less than 90°, with respect to a closest light incidence surface and a closest light guide plate side surface.
