Abstract

See full text

A light guide plate and a light source module are described. The light guide plate includes a main body, first stripe microstructures and second stripe microstructures. The main body includes a light incidence surface, a light-emitting surface and a light reflective surface opposite to the light-emitting surface. The light incidence surface is connected between the light-emitting surface and the light reflective surface. The light-emitting surface includes a first microstructure region and a second microstructure region arranged sequentially, and the first microstructure region is near the light incidence surface. The first stripe microstructures are disposed in the first microstructure region and extending along a direction from one side near the light incidence surface to the other side away from the light incidence surface. The second stripe microstructures are disposed in the second microstructure region along the direction. A gradient of each second stripe microstructure is gradually varied along the direction.
