Beschreibung
Zusammenfassung:	A light source module includes a light guide plate, a light source, a first prism sheet and a reflector. The light guide plate includes a light emitting surface, a bottom surface opposite to the light emitting surface and a light incident surface connected to the light emitting surface and the bottom surface. The light source is disposed at the light incident surface of the light guide plate, the light source is capable of emitting a light beam to the light incident surface. The first prism sheet is disposed on the light emitting surface of the light guide plate, the first prism sheet includes a plurality of first prism units, and surfaces of the first prism units face away the light emitting surface. The reflector is disposed on the bottom surface of the light guide plate, the light guide plate is located between the reflector and the first prism sheet. The reflector includes a plurality of micro structures, and surfaces of the micro structures face to the bottom surface of the light guide plate.
