1. A light source device comprising:
- a reference light source that emits reference color component light of a plurality of colors;
an excitation light source that emits an excitation light for a supplemental color component light;
a luminous body member including a luminous body that emits the supplemental color component light in response to the excitation light, the luminous body member including a plurality of supplementary color emission regions configured to emit different supplementary colors upon exposure to the excitation light; and
a combining unit that combines the reference color component light of the plurality colors and the supplemental color component light in such a way as to superimpose the supplemental color component light on light paths of the reference color component light of the plurality of colors.

5. A projection display apparatus comprising:
-
a reference light source that emits reference color component light of a plurality of colors; an excitation light source that emits an excitation light for a supplemental color component light; a luminous body member including a luminous body that emits the supplemental color component light in response to the excitation light, the luminous body member including a plurality of supplementary color emission regions configured to emit different supplementary colors upon exposure to the excitation light; a combining unit that combines the reference color component light of the plurality colors and the supplemental color component light in such a way as to superimpose the supplemental color component light on light paths of the reference color component light of the plurality of colors; and an imager that modulates light emitted from the combining unit.
