A display device includes: a first display part having a first screen; a second display part having a second screen; a casing which accommodates the first and second display parts, therein. A first display part area accommodates the first display part and a second display part area accommodates the second display part, which are formed in the casing. The movement mechanism includes a first in-plane direction rail which allows the first display part to move in the X-direction; and a second vertical direction rail, which allows the second display part to move in the Z-direction. The first in-plane direction rail allows the first display part area to move between the first display part and a neighboring area which is disposed adjacent to the first display part. The second vertical direction rail allows the second display part to move between the second display part and the first display part areas.
