A light source apparatus includes a light guide plate, light scattering micro-structures, at least a light-emitting module, and a front cover. The light guide plate has a first surface, a second surface opposite thereto, at least a light incident surface connecting the first and the second surfaces, a scattering area, and a reflecting area surrounding the scattering area. The light scattering micro-structures are disposed on at least one of the first and the second surfaces and within the scattering area. The light-emitting module is disposed beside the light incident surface and capable of emitting a light beam entering the light guide plate through the light incident surface. The front cover covers the reflecting area and has a light emerging area opposite to the scattering area. The light emerging area capable of being passed through by the light beam has a shape similar to a shape of the scattering area.
