Abstract: A light guide plate includes a plate body and a wedge-shaped body extended upward along a terminal of the plate body. A top surface of the plate body is connected smoothly with an inclined surface of the wedge-shaped body. The inclined surface is provided with multiple first inclined V-shaped structures arranged at intervals, and the top surface is provided with multiple first vertical V-shaped structures. The present invention also provides a backlight module having the light guide plate. When a light source is right opposite to a first spaced region (or a second spaced region) corresponding to and located between two first inclined V-shaped structures (or two second inclined V-shaped structures), lights emitted from the light source can be uniformed by the first inclined V-shaped structure and the second inclined V-shape structure in order to eliminate an uneven light and dark phenomenon generated on the inclined surface.
