Display device
A display device displays a virtual image of a first picture and a virtual image of a second picture by using a display medium. This display device includes a light source that emits light, a fixed screen, a movable screen, a driver, and a scanner. The fixed screen is fixedly disposed on an optical path between the light source and the display medium. The movable screen is also disposed on this optical path. The driver moves the movable screen along the optical path. The scanner scans the fixed screen and the movable screen with the light emitted from the light source, thereby forming the first picture on the fixed screen and the second picture on the movable screen.
