Abstract: The present invention provides a display device that can easily perform control for driving a movable screen. Display device includes light source that emits a light beam, scanner that causes the light beam from light source to scan, movable screen in which a first image is formed by transmitting the light beam from scanner, projection unit that projects the first image formed in movable screen on windshield and displays a virtual image of the first image in a space in front of windshield, and driver that causes movable screen to reciprocate in a first direction separating from scanner and in a second direction approaching scanner. Movable screen reciprocates in a posture inclined to moving directions of movable screen.

Abstract: A display device is provided and may include a light source that emits a light beam, a scanner that causes the light beam to scan, a movable screen in which an image is formed by transmitting the light beam from scanner, an optical system configured to project the image on a display medium, and a driver configured to cause the movable screen to reciprocate in moving directions. The image includes a first image and a second image. The movable screen reciprocates in a posture inclined with respect to the moving directions such that a second end of the movable screen is positioned closer to the scanner than a first end of the movable screen. The scanner forms the second image in the movable screen while the movable screen moves such that a forming direction of the second image is inclined with respect to a direction approaching the scanner.
