1. An image display device comprising:
- a transmitting unit for providing image information to illumination light and for transmitting said light as an optical image signal;
a reflecting part for reflecting said optical image signal;
a refracting optical part for projecting said optical image signal onto said reflecting part; and
a display unit for receiving said optical image signal and for displaying an image based on said image information, wherein said refracting optical part includes a path-bending unit for reflecting said optical image signal from a first lens unit to a second lens unit.

Abstract
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.
