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.

Dependent claims

A display device comprising:

a video display that displays a video on a video display surface, the video including a first video and a second video;
at least one optical element that is disposed on a part of the video display surface and has an incident surface on which the second video is incident, and an emitting surface from which the second video incident on the incident surface emits, and the incident surface and the emitting surface are parallel to each other;
and
a projector that projects a virtual image viewed by a user by projecting the first video displayed on the video display and the second video emitted from the emitting surface of the at least one optical element to a reflecting member the virtual image including a first virtual image and a second virtual image, the first virtual image corresponding to the first video, and the second virtual image corresponding to the second video.
