An image display apparatus includes an image generator for generating first light having image information, and a beam combiner for superimposing the first light and second light which is incident upon the beam combiner from a direction different from that of the first light, and for guiding the superimposed light to a pupil of an observer. Also provided is a reflector positioned in a direction different from the incident direction of the second light on the beam combiner. The first light is incident upon the reflector via the beam combiner, and is reflected back to the beam combiner after being reflected by the reflector.

The present invention relates to a multi-eye image displaying apparatus and a method using this apparatus. The apparatus comprises an image displaying element, provided for each of right and left eyes and a virtual image moving element for moving at least one of the virtual images for the right and left eyes in a horizontal direction. The image displaying element has an illuminating element for emitting light and, a display unit for displaying an image by using the light from the illuminating element. The image displaying element also has an optical system for projecting the light from the display unit toward a pupil of a viewer and, as a result, forming virtual images of the image to be displayed on the display unit in front of the pupil.
