Abstract: An optical device for an aerial display apparatus includes: a planar base member; a plurality of optical elements provided below the base member, each extending in a first direction and aligned in a second direction orthogonal to the first direction; a reflection layer provided in each of the optical elements and configured to reflect light; and an absorption layer provided on the reflection layer and configured to absorb light. Each of the optical elements has an incident surface and a reflection surface which are inclined with respect to a normal direction of the base member and are in contact with each other. The reflection layer is provided on the reflection surface. The optical device is arranged in such a manner as to receive external light on the incident surface.

Abstract: An aerial display apparatus includes: a display device configured to display an image; an optical device arranged to receive light from the display device and configured to reflect light from the display device to a side opposite to the display device to form an aerial image in an aerial space; a polarizing device arranged to receive light from the optical device and configured to transmit linearly polarized light; and a housing formed to surround the optical device and configured to fix the display device and the optical device with a space therebetween. A polarization axis of the polarizing device is parallel to a polarization axis of the display device.
