In a multiple image display device that is provided with a plurality of image display devices and that displays a single input image, the image display devices each divide the input image into division images that are individually displayed on the image display devices, and enlarge and display them. In particular, the image display device provided in an edge portion of the multiple image display device enlarges the division image toward a side opposite from the side of the edge portion. In this way, the edge portion of the input image is displayed on the multiple image display.
