Abstract
In the image observation apparatus of the invention, image light is guided to an observer'"'"'s eye by using a first refractive surface on which the image light from an image display device made incident, a reflective surface for reflecting the image light made incident from the first refractive surface, and an optical element having a second refractive surface for emitting the image light reflected from the reflective surface. A diffraction optical part integrated with the optical element is provided at or in the vicinity of the reflective surface of the optical element Thereby, an image observation apparatus in which chromatic aberrations in images can be satisfactorily corrected can be realized without complication and an increase in the size of the optical system.
