Abstract
A light guide plate is provided in the invention. The light guide plate has a light incident surface, a bottom surface and a light exit surface. The bottom surface is opposite to the light exit surface. The light incident surface is connected between the bottom surface and the light exit surface. The light guide plate includes a plurality of light guide units and a plurality of microstructure units. The plurality of light guide units are convex to the bottom surface and arranged to be disposed along a direction parallel to the light incident surface. The plurality of light guide units is connected to each other on the light incident surface. The plurality of microstructure units are disposed corresponding to the plurality of light guide units respectively. Each of the microstructure units includes a plurality of microstructures. The invention further provides a backlight module having this light guide plate.
