Abstract: The invention provides a light source module including a light guide plate and light emitting elements. The light guide plate includes a main plate body and a plurality of optical microstructures. The main plate body has a light emitting surface and a back surface opposite to each other, and a light incident surface connected therebetween. The optical microstructures are formed on the back surface. Each optical microstructure includes at least two sections connected to each other, each section having a reflective surface. The light emitting elements are disposed on the light incident surface, and light emitted by each of the light emitting elements is reflected by at least some of the reflective surfaces and transmitted to the light emitting surface. In any optical microstructure, the reflective surfaces are not parallel to each other.

Abstract: A light source module including a light guide plate, a first light source and a plurality of first optical microstructures is provided. The light guide plate has a first incident surface and a bottom surface connected to the first incident surface. The first light source is disposed on a side of the first incident surface of the light guide plate. The first optical microstructures are disposed on the bottom surface. Each of the first optical microstructures has a first light receiving surface disposed toward the first light source. Each of the first light receiving surfaces of a first portion of the first optical microstructures has a first edge at a junction with the bottom surface, and a perpendicular bisector of the first edge passes through the first light source.

Abstract: A light guide plate (LGP) and a light source module are provided. The LGP includes a plate body, first microstructures and second microstructures. The plate body has a first light incident surface, a second light incident surface adjacent to the first light incident surface and a first surface connected thereto. The first microstructures are located on the first surface, and each has a first optical surface facing the first light incident surface. Two sides of each first microstructure respectively have a first edge portion. One of the first edge portions faces and is inclined relative to the second light incident surface, and there is a first included angle between the first edge portion facing the second light incident surface and the first surface. The second microstructures are located on the first surface, and each second microstructure has a second optical surface facing the second light incident surface.
