<p>An observation optical system (1) is configured to introduce light fluxes from a plurality of display elements to an exit pupil (S) via an optical element (11, 12) having a plurality of optical units, and to present a combined and enlarged image (200). 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 (B1, B2) that has the highest refractive power among the plurality of reflective surfaces has a symmetrical plane. When a decentering section (y1z1, y2z2) 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.</p> |
