Abstract

An aerial image display device includes a display component, an imaging component, and a first limiter. The display component has a display surface for displaying an image. The imaging component has a first reflecting surface and a second reflecting surface that are arranged perpendicular to each other along an image formation plane of the imaging component. The imaging component forms an aerial image of the image in a display area that is symmetrical with the display surface with respect to the image formation plane. The first limiter is disposed closer to the display component than the imaging component. The first limiter limits an incident angle of incident light incident on the imaging component. The first reflection surface and the second reflection surface are inclined by an angle between 30° and 60° with respect to a median plane that includes a perpendicular of each of the display surface and the image formation plane.
