ABSTRACT:
A display unit which displays a plurality of objects viewed as being located at different depthwise positions by the viewer so as to exhibit an image with depthwise feeling, includes: a single display portion including a far-distant display zone and a near-distant display zone, a polarized beam splitting element in front of the near-distant display zone, a polarized beam changing element in front of the far-distant display zone, and a total reflection mirror for reflecting an image beam emitted from the far-distant display zone, onto the polarized beam splitting element. An image beam emitted from the far-distant display zone is transmitted through the polarized beam changing element, then is reflected at the total reflection mirror, and thereafter is reflected by the polarized beam splitting element before it is viewed by the viewer.
