Abstract
A light guide plate includes a plurality of optical microstructures. The plurality of optical microstructures are disposed on a first surface of the light guide plate. An absorption layer including a plurality of first absorption units and a reflection layer including a plurality of reflection units are also provided on the light guide plate. The reflection units respectively overlap the optical microstructures. The first absorption units respectively overlap at least a part of the reflection units. The at least a part of the reflection units are located between the corresponding first absorption units and the optical microstructures. The light guide plate of the disclosure has less light leakage on a non-light emitting surface side. A light source module with the light guide plate is also proposed. The light source module of the disclosure has better light energy utilization rate and is adapted for full lamination with other functional modules.
