Abstract: An aerial display apparatus includes: a display device which includes a display surface on which a first image is displayed, and which emits display light from the display surface; a mirror device which is disposed obliquely with respect to the display surface of the display device, which reflects the display light that has been emitted from the display device to form an aerial image at a position that is plane-symmetrical to the display device; and a display device which is disposed between the mirror device and the aerial image, which allows the display light that has been reflected by the mirror device to be transmitted therethough, and which displays a second image.

Abstract: An aerial display apparatus includes a display device (22) which includes a display surface on which an image is displayed, and which emits display light from the surface, a light control device (40) which includes a plurality of transparent regions (41) and a plurality of light-shielding regions (42) that are arranged in an alternating manner and are obliquely disposed with respect to a first direction that is orthogonal to the surface, and which allows the light that has been made incident on the region (41) to be transmitted therethrough, and shields the light that has been made incident on the region (42), and a mirror device (10) which is disposed in parallel to the surface, which reflects the light that has been transmitted through the device (40), and which forms an aerial image (30) at a position that is plane-symmetrical to the device (22).

Abstract: An aerial display apparatus includes: a display device which displays an image; a mirror device which includes a plurality of optical elements each including two reflective surfaces that are orthogonally disposed, which reflects display light from the display device, and which forms an aerial image at a position that is plane-symmetrical to the display device; and a light shielding member which is disposed on an optical path between the display device and the aerial image, which includes an opening that allows a portion of incident light to pass through, and which shields light incident on a region other than the opening.
