Abstract

A display device includes a screen to form an intermediate image with light; a concave mirror, and a first mirror disposed between the screen and the concave mirror. The first mirror includes a first reflective area to reflect the light emitted from the screen to the concave mirror; a second reflective area to reflect the light emitted from the concave mirror to an area where a virtual image is formed; and a common reflective area in which the first reflective area and the second reflective area at least partly overlap on each other.
