1. An image display device comprising:
- an optical imaging arrangement for providing image information to illumination light and for transmitting the image information as an optical image signal;
a projecting optical arrangement for receiving the optical image signal and for projecting the optical image signal;
a display for receiving the optical image signal through said projecting optical arrangement and for displaying an image based on the image information; and
a plane mirror for reflecting the optical image signal output from said projecting optical arrangement on said display,wherein said image display device has a bottom positioned on a plane that orthogonally intersects a plane on which receiving surface of said display is positioned; and
wherein at least a part of said optical imaging arrangement is disposed in a placement space defined by linking with a line, respectively;
a first point present on the basis of an image displayed on said display and furthest from the center of the image with a first projected point formed by projecting the first point to said bottom from the direction normal to the bottom;
a second point on said plane mirror on which light toward the first point is reflected with a second projected point formed by projecting the second point to said bottom from the direction normal to said bottom; and
a third point on said projecting optical arrangement on which light toward the second point is reflected with a third projected point formed by projecting the third point to said bottom from the direction normal to said bottom.
