Patent ID: 7199935

Claim:
An image display apparatus comprising: a single image forming device which forms an original image; and a first optical system and a second optical system which are disposed on both sides of a central plane which includes a central axis of the image forming device, the first optical system guiding light from the image forming device to a first eye of an observer placed near a pupil of the first optical system, and the second optical system guiding light from the image forming device to a second eye of the observer placed near a pupil of the second optical system, wherein, when light traveling from the image forming device to each of the pupils is inversely traced from the pupil, each of the first and second optical systems includes: a first surface which reflects the inversely traced light from the pupil in a direction away from the central plane; and a second surface which reflects the inversely traced light from the first surface in a direction away from the central plane, wherein each of the first and second optical systems is arranged in plane symmetry with respect to a plane perpendicular to the central plane.
