The invention provides a stereoscopic display to display a high-quality
three-dimensional video which can be viewed without using polarizing
glasses. A stereoscopic display according to the present invention
includes an electronically-formed, multi-viewpoint light beam group and
an image-forming device to reproduce a conjugate image of the
multi-viewpoint light beams. The stereoscopic display further includes a
cylindrical, or partially cylindrical parallax barrier and a rotating
light-emitting array as a multi-viewpoint-light-beam forming device. In
addition, the stereoscopic display further includes a polarizing element
and a polarization separation device to increase the display contrast.
The numerical aperture of the rearmost optical element is preferably
increased in order to increase the viewing area, and a reflective optical
element with a large aperture is used as the image-forming device. The
light-emitting array is formed of lightweight, thin-film light-emitting
elements with which electronic rotational scanning is possible.
