The color separation/light combining element included in an illuminator has at least one first region and at least one second region. The light ray flux contains a first light ray flux outputted from the first light emission unit and a second light ray flux outputted from the second light emission unit. a wavelength conversion element, a diffusive reflection element, and the color separation/light combining element are so disposed that part of the first light ray flux is incident on the diffusive reflection element via the first region, the other part of the first light ray flux is incident on the wavelength conversion element via the first region, a part of the second light ray flux is incident on the wavelength conversion element via the second region, and the second region combines the converted light with a part of light reflected off the diffusive reflection element to produce illumination light.
