The first image-forming element and the second image-forming element respectively form a first original image and a second original image that correspond to different viewing fields from the exit pupil position.

摘要： An observation optical system is configured to introduce light fluxes from a plurality of display elements to an exit pupil via an optical element having a plurality of optical units, and to present a combined and enlarged image. Each display element is configured to display an original image. One optical unit of the observation optical system has a plurality of reflective surfaces. A reflective surface that has the highest refractive power among the plurality of reflective surfaces has a symmetrical plane. When a decentering section is defined as a section that contains the symmetrical plane, the plurality of optical units are arranged so that the decentering sections of the plurality of optical units are parallel to each other. The reflective surfaces having the highest refractive power in different optical units intersect each other.
