Each of the display units includes a screen on which an object image is formed; and a diffractive optical element that includes a first surface and a second surface that is situated opposite to the first surface, the diffractive optical element diffracting image light of the object image that enters the first surface, and causing the image light to exit the first surface, the diffractive optical element displaying a virtual image of the object image on a side of the second surface such that the virtual image is superimposed on a background. The diffractive optical elements of a plurality of the diffractive optical elements included in the display units are each arranged to at least partially surround a specified axis in a state in which the second surface faces the specified axis.
