Patent attributes
A display device has a projector having a light guide plate that guides light incident from an end portion and deflects the light guided to emit the light from a projection surface facing a viewer in a first direction, the projector being configured to emit light from the projection surface to project an image in a space viewable by the viewer, and a rotator configured to rotate the projector around the first direction. When a first end on the projection surface is located at a first position being an upper side in a second direction orthogonal to the first direction, the image is viewed as a stereoscopic image by the viewer. When the rotator rotates the projector and the first end is located at a second position different from the first position, the image is viewed as a planar image by the viewer.
