AI summary

An aerial image display device is provided which can be folded into a small size and freely carried. The aerial image display device includes a display substrate displaying a contactless interface, an optical plate connected to the display substrate by a hinge member, and a support structure capable of fixing the display substrate and the optical plate at a predetermined angle. When the contactless interface is displayed on the display substrate with the display substrate and the optical plate being fixed at the predetermined angle, the contactless interface is displayed as an aerial image via the optical plate in air on the opposite side of the optical plate. The display substrate, the optical plate and the support structure can be stacked on each other and folded into a plane.
