In an image display device, an image controller controls a floating image and a direct view image so as to be linked to each other. The image controller displays a given object as the floating image, and displays the floating image such that the given object displayed as the floating image is shifted in a specified first direction from a displayed position of the floating image to a second image screen. The image controller executes a process associated with the given object during or after the shift of the given object, and displays, on the second image screen, a two-dimensional image on which the executed process is reflected.
