Abstract:
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 below a horizontal plane including 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, and said display is placed above the horizontal plane including the optical axis of said projective optical system, and wherein said display is so placed as to be substantially perpendicular to the optical axis of said projective optical system.
