A light source device (3) includes a plurality of light sources (2a) arranged in a first direction, a first cylindrical lens (8), which light beams from the plurality of light sources enter, and a lens unit (9), which light beams from the first cylindrical lens enter. A generating line of the first cylindrical lens is parallel to the first direction. The lens unit is provided with a plurality of cylindrical lenses (12) disposed so as to correspond respectively to the plurality of light sources, and a generating line of each of the plurality of cylindrical lenses intersects with the first direction. An arrangement of a second cylindrical lens included in the plurality of the cylindrical lenses is determined independently of the adjacent one of the cylindrical lenses. |
