Abstract:
1. A projector comprising: a first solid-state light source device which includes a first solid-state light source emitting main excitation light, and a fluorescent layer converting main excitation light to light including a first color light component and a second color light component different from the first color light component, and emitting converted light; a second solid-state light source device which includes a second solid-state light source emitting a third color light component different from the first color light component and the second color light component; a light modulation device modulating the first color light component, the second color light component, and the third color light component in accordance with image information; a projection optical system projecting the modulated light components from the light modulation device as a projection image; and a third solid-state light source device which includes a third solid-state light source emitting auxiliary excitation light, wherein the fluorescent layer is configured such that auxiliary excitation light is input thereto in a direction different from a direction in which main excitation light is input, and the fluorescent layer is configured to convert auxiliary excitation light to light including the first color light component and the second color light component, and to emit converted light.
