Abstract: To provide a display device that can suppress generation of a double image. Display device includes plate-shape windshield having translucency and a projection unit that projects light expressing an image onto windshield such that the light is reflected toward a user by windshield. The projection unit changes a display distance between an eye of the user and a position of an image visually recognized as a virtual image by the user through windshield by the light projection. Windshield is formed such that a wedge angle that is of an angle formed between a front side and a back side at a region located at any level of windshield is continuously decreased with increasing level.

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.
