Abstract
A light guide plate includes at least one light incident surface, a light emitting surface adjacent to the light incident surface, and a bottom surface opposite to the light emitting surface. A geometrical center of the bottom surface is depressed and a tetrahedral cone is defined by the geometrical center and four edges of the bottom surface. A plurality of V-shaped projections is arranged on each surface of tetrahedral cone. Each of the V-shaped projections has a same shape. A distribution density and sizes of the V-shaped projections progressively increase with increasing the distances from the edges to the geometrical center of the bottom surface. A backlight module using the light guide plate is also provided in the present invention. The light guide plate can improve the evenness of light emitting of the backlight module.
