Abstract A light source apparatus including a light guide plate, a first light emitting unit, and a second light emitting unit is provided. The light guide plate has a first surface, an opposite second surface, a first side surface, and an opposite second side surface. The first light emitting unit is disposed beside the first side surface for providing a first light beam. The second light emitting unit is disposed beside the second side surface for providing a second light beam. The first light emitting unit has a central line passing through a geometric center of the first light emitting unit and being perpendicular to the first side surface. The second light emitting unit has a central line passing through a geometric center of the second light emitting unit and being perpendicular to the second side surface. The central lines do not coincide with each other.
