Beschreibung
Zusammenfassung:	An illumination device of the present disclosure includes: a first light source unit (11) that emits first light of a first wavelength band; a first spatial light modulator (13) where the first light from the first light source unit (11) enters; a second light source unit (14) that emits second light of a second wavelength band; an integrator optical system (20) including a first fly-eye lens (21A) where the second light from the second light source unit (14) enters and generating illumination light for an illumination target (16) on a basis of the first light having been modulated by the first spatial light modulator (13) and the second light from the second light source unit (14); and a multiplexing optical system (50) that multiplexes the second light having entered the first fly-eye lens (21A) and the first light having been modulated by the first spatial light modulator (13), in an optical path between the first fly-eye lens (21A) and the illumination target (16).
