Abstract
Disclosed is a light guide plate having secondary light guide structures, which has a top face and a bottom face at least one of which is provided with a plurality of secondary light guide structures and primary light guide structures that are alternately distributed, wherein a tangential line to a light incidence surface of the secondary light guide structure forms an inclined angle less than 40 degrees with respect to a reference plane. The primary light guide structures are roughened surface in a dot-matrix form. The secondary light guide structures and the primary light guide structures cooperate to guide light into the light guide plate so as to enhance the probability of light that is diffracted or reflected by the primary light guide structures to emit out of the light guide plate.
