Abstract
In an image display apparatus, an image data supply means is readily connected with an image display means through a channel, which are installed at positions remote from each other. The present invention provides an image data supply means for supplying image data, an optic-spatial transmission means on a transmission side for emitting optical beam which is modulated in accordance with the image data, optic-spatial transmission means on a reception side for receiving the optical beam emitted by the optic-spatial transmission means on the transmission side, and demodulating the optical beam to recover the image data, and an image display means for displaying an image based on the image data recovered by the optic-spatial transmission means on the reception side.
