[Problem] To make it possible to display a stereoscopic image and also to display an image for conventional two-dimensional display, and furthermore to make it possible to perform stereoscopic viewing of a radiographic image without burdening the viewer. [Solution] A display device provided with a display unit comprising a first display screen which displays an image for the right eye, and a second display screen which is positioned adjacent to the first display screen and displays an image for the left eye. The display device can switch between a first set-up state where the first display screen and the second display screen are adjacent in the vertical direction, and a second set-up state where the first display screen and the second display screen are adjacent in the horizontal direction. The display device displays the image for the right eye and the image for the left eye on the first and second display screens when in the first set-up state, displays the image for two-dimensional display on the first and second display screens when in the second set-up state, and furthermore displays an indicator for stereoscopic viewing confirmation on at least one of the first and the second display screens when in the first set-up state.[Problème] Permettre laffichage dune image stéréoscopique ainsi que laffichage dune image pour affichage bidimensionnel classique, et en outre permettre la visualisation stéréoscopique dune image radiographique sans effort du spectateur.
