Abstract: A multiview three-dimensional image display apparatus comprises: a light source, a shutter plate for selectively passing light from the source; a diffuser immediately adjacent the shutter plates an optical element in front of the diffuser for forming a viewing zone; and a transparent display immediately adjacent the optical element for displaying multiview images thereon, wherein the multiview images are displayed based on a time-multiplexing technique and the viewing zone is formed in front of the transparent display. The apparatus can be readily modified into a multiview apparatus that includes a plurality of light sources. Since a plurality of viewing zones can be simultaneously formed in the apparatus, it is possible for multiple viewers to simultaneously observe the same three-dimensional image.
