Abstract
A floating image display device, configured to generate a floating image, is provided. The floating image display device includes an image module and at least one transflective optical element. The image module is configured to provide a first image. The transflective optical element includes a first reflective surface and a second reflective surface. The first image is located between the first reflective surface and the second reflective surface. Each of the first reflective surface and the second reflective surface includes a curved surface and has no opening on an optical axis thereof. The second reflective surface is a transflective surface. The first reflective surface and the second reflective surface are configured to re-converge rays from the first image to form a second image. The second image is a floating image.
