Zusammenfassung:	The utility model provides a light guide plate. The light guide plate comprises a body and a plurality of grooves. The body is provided with a first side face, a second side face, a third side face, a fourth side face, a bottom face and a top face, the bottom surface and the top surface are respectively connected among the first side surface, the second side surface, the third side surface and the fourth side surface. In addition, the plurality of grooves are recessed from the bottom surface toward the top surface. Each groove is provided with a first surface and a second surface which are opposite, the first surface and the second surface are inclined relative to the bottom face, and the first surface and the second surface are symmetrically arranged. The utility model further provides an area light source module comprising the light guide plate. The first surface and the second surface which are symmetrically arranged on the groove of the light guide plate can effectively improve light emitting efficiency,
