Abstract:
1. An image display apparatus comprising: a light source system that emits light having a first wavelength and light having a second wavelength switched with time; a light modulator that modulates the light having the first wavelength and the light having the second wavelength emitted from the light source system; an optical path adjustment system that shifts the optical paths of the light having the first wavelength and the light having the second wavelength modulated by the light modulator from each other; and a projection system that projects the light having traveled via the optical path adjustment system, wherein the optical path adjustment system includes: a wavelength selecting surface that reflects the light having the first wavelength and transmits the light having the second wavelength; and a mirror system disposed in such a way that the optical paths of the light having the first wavelength and the light having the second wavelength having traveled via the wavelength selecting surface are shifted from each other but the traveling directions thereof are the same.
