Light source module

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.
