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

Abstract
An image display system includes a light valve 14 for providing image information to light converged by a converging lens 13 and for emitting the light, a projective optical system 20 including a refractive optical lens 21 for projecting the light from the light valve 14 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 a display 30 for receiving the light from the projective optical system 20 by way of a receiving surface 30A, wherein the light valve is placed away from an optical axis 23 of the projective optical system 20 and between a front surface of the display 30 and a rear surface of the projective optical system 20.
