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.
