Abstract
A light source module including a casing, a light guide plate, at least one light emitting element, and a reflector is provided. The light guide plate includes a plate body and an optical microstructure array. The optical microstructure array is located at a top surface of the plate body and includes a plurality of microstructure units. The microstructure units are recessed from the top surface towards the bottom surface and are shaped as inverted square pyramids, and a pyramid portion of each of the inverted square pyramids is formed by at least four surfaces. Each of the microstructure units includes two opposite first surfaces and two opposite second surfaces arranged in an alternating manner. Further, in each of the microstructure units, angles included between the two first surfaces and the top surface are identical, and angles included between the two second surfaces and the top surface are identical.
