Abstract: A three-dimensional (3D) image display apparatus, a 3D image display method, and a 3D image generating and displaying system are provided. The 3D image display apparatus includes a display displaying a plurality of element images, an exit pupil array controlling directions of rays that exit from the plurality of element images, an active shutter configured to transmit or block rays through each of the exit pupils, and a processor configured to generate the plurality of element images from a multi-viewpoint image group, arrange each of the plurality of element images on an expanded region including a first region corresponding to a first exit pupil for rays transmitted by the active shutter and a second region corresponding to a second exit pupil for rays blocked by the active shutter, and synchronously display the plurality of element images on the display while transmitting or blocking of the rays.
