Abstract
A display device includes: a display that generates image display light; a concave mirror that reflects the image display light such that the image display light is projected onto a transparent member; and a drive mechanism that moves the display in a range in which a distance from the concave mirror to the display is smaller than or equal to a reference distance at which the image display light traveling from the concave mirror to the transparent member becomes parallel light.
