摘要： A light guide plate including a first surface, a second surface, at least one light incident surface, and a plurality of groove sets is provided. The light incident surface connects the first surface and the second surface. The groove sets are separately disposed on the second surface. Each of the groove sets includes a plurality of curved grooves. Each of the curved grooves has a curved inclined reflective surface and a curved back-to-light surface connected thereto. The curved inclined reflective surface is inclined with respect to the first surface. The curved grooves of each of the groove sets curve toward the same curving direction. The curved inclined reflective surface of one of two adjacent curved grooves is connected to the curved back-to-light surface of the other one of the two adjacent curved grooves through a connection surface. A light source module is also provided.
