An image display device comprises an optical imaging arrangement for
providing image information to illumination light and for transmitting
the light as an optical image signal; a display for receiving the optical
image signal and for displaying an image based on the image information;
and a projecting optical arrangement including a reflecting part having a
reflecting surface for reflecting the optical image signal, and a
refracting optical part having a refracting surface for projecting the
optical image signal onto the reflecting part. At least one of the
reflecting surface and the refracting surface is aspherical.
