A multiplex image display device prevents onscreen input buttons from appearing at the same positions. A 'command area' refers to an area of the display screen where the user can enter a command for manipulating one of images being simultaneously displayed on the single display section for individual viewing from different directions. In the multiplex image display device, the positioning control section controls the positioning of the command areas so that a command area for one of the images being simultaneously displayed on the display section is displayed at a different (i.e., non-overlapping) position on the display section from a command area for another one of such images.
