An image display apparatus includes: a light source system that emits light having a first wavelength and a second wavelength switched with time; a light modulator that modulates the light having the first wavelength and 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 second wavelength modulated by the light modulator from each other; and 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 mirror system disposed in such a way that the optical paths of the light having the first wavelength and the second wavelength having traveled via the wavelength selecting surface are shifted from each other.
