Beschreibung
Zusammenfassung:	A projector includes an illumination system that outputs illumination light containing white light, which is visible light, and infrared light, an image formation section that forms image light from the illumination light, a projection system that projects the image light on a projection surface and radiates the infrared light onto the projection surface, and a detection section that detects a pointing element based on reflected light formed of the radiated infrared light. The image formation section includes a light-exiting-side polarizer that transmits the visible light in such a way that the light-exiting-side polarizer transmits light formed of one polarization component and blocks light formed of another polarization component, and the light-exiting-side polarizer transmits the infrared light in such a way that the light-exiting-side polarizer transmits the two polarization components of the infrared light.
