Abstract
An image display apparatus includes a first image carrier along with an apparatus for inputting an image signal. An erasable image is formed on the first image carrier in accordance with the image signal input from the image signal input apparatus. A display area displays the image formed on the first image carrier. A second image carrier, which is associated with the first image carrier, contains a visible image which is photoelectrically read and converted to an image signal. The visible image carried on the second image carrier is automatically erased after the visible image is converted to an image signal.
