Abstract: A light source module including a light guide plate, a light source, and an adhesive material is provided. The light guide plate having a light-coupling region and a light-emitting region includes a light-incident surface, a first and a second surfaces opposite to the first surface, a plurality of first and second microstructures. The light-coupling region is located between the light-incident surface and the light-emitting region. The light-incident surface is connected to the first and the second surfaces. The first microstructures are disposed in the light-emitting region and protrude from the first surface. The second microstructures are disposed in the light-coupling region and protrude from at least one of the first and the second surfaces. A shape of the first microstructures is different from that of the second microstructures. The light source is disposed beside the light-incident surface. The adhesive material is disposed between the light source and the light-incident surface.

Abstract: A backlight module includes first and second light emitting layers. The first light emitting layer is disposed above the second light emitting layer and each includes at least one light guide plate and light source disposed next to the respective light guide plate. Each light guide plate has at least one light transmissive region and light exit region. Each light transmissive region of the first light emitting layer corresponds to each light exit region of the second light emitting layer. Each light exit region of the first light emitting layer corresponds to each light transmissive region of the second light emitting layer. Each light source is next to each light transmissive region. Each light transmissive region is between each light source and light exit region. Each light exit region of the first light emitting layer corresponds to each light transmissive region and light source of the second light emitting layer.
