Abstract
A display device includes: a video display that displays a video for projecting a virtual image onto a target space on a video display surface; an optical element; and a projector. The optical element moves a partial video, which is a part of the video displayed on the video display surface, to a position distant from the video display in a projection direction in which the video is projected. The projector projects a virtual image viewed by a user by projecting light output from the video display and the optical element to a reflecting member. The optical element has an incident surface on which the partial video is incident, and an emitting surface from which the partial video incident on the incident surface emits. The incident surface and the emitting surface are parallel to each other.
