A flat plate is provided to the cone sheet, and a plurality of circular cones are arranged two-dimensionally on the light-incident surface of the flat plate. The central axes of the circular cones are parallel to each other. The transparent/scattering state switching element is capable of switching between a state for transmitting incident light and a state for scattering the light. By this configuration, a light source device is obtained having high directivity, high luminance, and no limitations on the mounting position of the light source.
