Patent ID: 7144113

Claim:
A virtual image display apparatus comprising: an optical unit for projecting an image; and a translucent reflecting means for reflecting the image from the optical unit, so that the image can be recognized by an observing person at its observing points as a virtual image, wherein the image from the respective observing points is overlapped in the distance, wherein the optical unit comprises: a pair of optical projection systems, each having a display device for displaying a respective image thereon, a light source for illuminating the display device and a projection lens for projecting the image of the display device, the pair of optical projection systems projecting the respective images corresponding to right and left eyes of the observing person; and an image location optical system arranged at an image focus location at which the respective images from the pair of optical projection systems are formed, wherein the image location optical system comprises: an optical device for forming a conjugated relation between an exit pupil of the projection lens and the observing points of the observing person; and an optical diffusion device for diffusing light rays to an extent that the light rays to one of the observing points may not reach the other observing point.
