An image display device which is provided with an image display panel, and a housing which houses the image display panel. In the front wall of the housing, an image display window makes the screen of the image display panel viewable from the outside. In the rear wall of the housing are two housing sections, each being configured by connecting together a recessed section provided in the rear wall, and a cover which covers the opening of the recessed section. On the recessed section-side connecting surface from the surfaces on which the recessed section and the cover of each housing section are connected, screw members are screwed at a plurality of areas along the inner circumference of the connecting surface by penetrating the cover. The distances between the adjacent screw members in the two housing sections are different from each other.
