Abstract
An image display apparatus having a compact size and appropriately achieving a larger field angle is disclosed while it has two optical systems guiding light from a single image forming device to both eyes. The apparatus has the single image forming device forming an original image, and a first and a second optical system disposed on both sides of a central plane including a central axis of the image forming device. The optical systems guide light from the image forming device to a first and a second eye of an observer, respectively. When light traveling from the image forming device to each pupil of the optical systems is inversely traced from the pupil, each system includes a first surface reflecting the inversely traced light from the pupil in a direction away from the central plane, and a second surface reflecting the inversely traced light from the first surface in a direction away from the central plane.
