An image display device includes: a camera mounted on a vehicle and configured to take an image representing a view behind the vehicle; an image cutouter configured to cut out a second image, from a first image taken by the camera, based on a reference cutout position in the first image; and a display configured to display the second image cut out by the image cutouter. The image cutouter is configured to, when a display object in the first image is to move in a first direction due to change of an orientation of the vehicle, execute a processing in which a cutout position for the second image at a first time point is moved from the reference cutout position in a second direction opposite to the first direction.
