Abstract: A light source device includes: a light source having an upper surface including a light-emitting surface, the light source comprising a plurality of light-emitting parts arranged in a two-dimensional array; a lens located above and spaced apart from the light-emitting surface of the light source, wherein the lens comprises an optically functional part, and a flange part located along an outer periphery of the optically functional part; and a support part formed of a light-shielding material and configured to support at least the flange part of the lens. A surface area of a first surface of the optically functional part is greater than a surface area of a second surface of the optically functional part. The flange part defines at least one first recess in a surface located at a same side as the second surface.
