Abstract
An aerial image display device includes a display device, an optical system, and a distance-varying portion. The optical system forms, as a real image, an aerial image from image light emitted from the display device. The distance-varying portion is located opposite to an eye of a user across the aerial image and at a defocus position for the eye of the user when the eye of the user is at a focus position for the aerial image. The distance-varying portion has a varying distance, by location, from a virtual imaging plane of the aerial image.
