Abstract

A light guide plate including a first substrate, a second substrate opposite to the first substrate, a plurality of first microstructures, a plurality of second microstructures, and a plurality of third microstructures is provided. The first substrate has a light emitting surface, a first bottom surface, and a light incidence surface. The second substrate has a top surface and a second bottom surface. The top surface is located between the first substrate and the second bottom surface. The first microstructures and the second microstructures are disposed on the light emitting surface and the second bottom surface respectively and extend along a first direction parallel to the light incidence surface respectively. The third microstructures are connected between the first bottom surface and the top surface and extend along a second direction perpendicular to the light incidence surface respectively. A light source module is also provided.
