A light guide plate includes an incident surface, an emission surface, and a bottom surface. The emission surface intersects with the incident surface and is substantially perpendicular to the incident surface. The bottom surface intersects with the incident surface and is opposite to the emission surface. The light guide plate further includes at least one light diffusing portion protruding from the incident surface. The light diffusing portion has a reflective hole located at (i.e., extending from) the bottom surface, the reflective hole protruding less than a thickness of the light guide plate. A backlight module, adopting the above-described light guide plate, further includes at least one corresponding light source positioned beside the incident surface of the light guide plate. The light source includes a luminescent surface facing a corresponding light diffusing portion of the light guide plate.
