A light source module includes a light-emitting device, a light guide pipe, a wave plate, and a polarizer. The light-emitting device emits a beam. The light guide pipe includes a recessed curved surface, an output surface, a first convex surface, and a second convex surface. The recessed curved surface faces the light-emitting device. The output surface is opposite to the recessed curved surface. The first convex surface connects the recessed curved surface with the output surface. The second convex surface connects the recessed curved surface with the output surface and is opposite to the first convex surface, wherein the beam enters the light guide pipe through the recessed curved surface, and leaves the light guide pipe through the output surface. The wave plate is disposed on a path of the beam from the output surface. The polarizer is disposed on a path of the beam from the wave plate.
