Abstract: A light source unit includes a light emitting substrate, a light shielding body and a lens array. The light emitting substrate includes a plurality of light emitting elements. The light shielding body blocks unnecessary light of the light emitting elements. The lens array includes a plurality of lenses. The lens array is fixed directly to the light emitting substrate in a state in which the light shielding body is positioned between the light emitting substrate and the lens array.

Abstract: A lens array includes a flat plate-shaped base part, a plurality of lenses, a plurality of columnar light guiding parts and a plurality of light shielding parts. The lenses are formed on one surface of the base part. The columnar light guiding parts are formed on another surface of the base part at points corresponding to the lenses. The light shielding parts are formed at least on lateral surfaces of the light guiding parts.
