Beschreibung
Zusammenfassung:	The present invention implements a light source device that achieves suppression of luminance degradation and suppression of uneven illuminance using a simple optical system configuration. A light source device (1) is provided with: a light source unit (2) that includes a plurality of LED elements (3); a first optical system (5) that narrows the divergence angle of light emitted from the light source unit (2) without collimating the light; a second optical system (7) that condenses light emitted from the first optical system (5); and an integrator optical system (8) that has an incidence surface disposed at a focus position (7f) of the second optical system (7).
