Light source module

Abstract

A light source module including a light guide plate, a first light source, a second light source, a plurality of first optical microstructures and a plurality of second optical microstructures is provided. The first light source and the second light source are disposed corresponding to a first light incident surface and a second light incident surface of the light guide plate respectively. The plurality of first optical microstructures corresponding to the first light source and the plurality of second optical microstructures corresponding to the second light source are disposed on a bottom surface of the light guide plate, and each have a pattern reflective surface facing one of the first light source and the second light source and a off-axis reflective surface facing the other of the first light source and the second light source. A pattern reflective angle included between the pattern reflective surface and a virtual extension surface of the bottom surface is greater than or equal to
