Image display system
First Claim
1. An image display system characterized in that said system comprises:
- transmission means for providing image information to illuminating light and for transmitting the illuminating light as an optical image signal;
projective optical means provided with a refractive optical unit for projecting said optical image signal transmitted thereto from said transmission means and a reflective optical unit for reflecting said optical image signal projected by said refractive optical unit; and
display means for receiving said optical image signal by way of said projective optical means and for displaying an image based on said image information, and characterized in that said transmission means is placed away from an optical axis of said projective optical means, and is also placed between a front surface of said display means and a rear surface of said projective optical means.

Abstract
An image display system includes transmission means 10 provided with a light emitting body 11 for emitting light, a parabolic mirror 12 for reflecting the light emitted out of the light emitting body 11 and for emitting the light as substantially-parallel light, a converging lens 13 for converging the parallel light from the parabolic mirror 12, and a light valve 14 for providing image information to the light converged by the converging lens 13 and for emitting the light, projective optical means 20 provided with a refractive optical lens 21 for projecting the light from the transmission means 10 and a convex mirror 22 for reflecting the light from the refractive optical lens 21 by using a reflecting surface thereof having negative power and for enlarging and projecting the reflected light, and display means 30 for receiving the light from the projective optical means 20 by way of a receiving surface 30A thereof and for displaying an image based on the image information on an image display screen 30B thereof, the transmission means 10 being placed away from an optical axis 23 of the projective optical means 20 and the transmission means 10 being placed between a front surface of the display means 30 and a rear surface of the projective optical means 20.
