Abstract
An image display apparatus has an observation room for housing an observer, and the side faces, floor face, and ceiling face of the observation room are used as screens, onto which images displayed on a smaller number of image display devices than the number of screens are projected. At least one image display device displays, on a time-division or screen-division basis, images to be projected onto two or more screens so that images are projected onto all of the screens.
