An optical axis of the image pickup optical system is substantially aligned with an axis that is an extension of the eye-ball optical axis in an optical path of the display optical system. The apparatus further has an optical path separating element for separating an optical path of the image pickup optical system from the optical path of the display optical system. Each of the display optical system and the image pickup optical system has a plurality of decentered reflective surfaces having curvature. The light from the display device is alternately folded in directions along the eye-ball optical axis by the plurality of reflective surfaces of the display optical system to be guided to the eye. The light from the outside is alternately folded in directions different from an observation direction by the plurality of reflective surfaces including the optical path separating element. The image pickup optical system has a stop and a rear optical system placed behind the stop. The image pickup optical system also has a surface having a negative power and a surface having a positive power in that order toward the stop in the optical path before the stop. The rear optical system is a refracting optical system or a reflecting optical system having a positive power.
