Patent ID: 7233441

Claim:
A stereoscopic display, comprising: a multi-viewpoint-light-beam-group generating device which generates an electronically-formed, multi-viewpoint light beam group; and an image-forming device which reproduces a conjugate image of a stereoscopic image formed by the multi-viewpoint light beam group; the multi-viewpoint-light-beam-group generating device including a cylindrical parallax barrier and a cylindrical light-emitting array; electronic scanning being performed on the cylindrical light-emitting array by electronically activating and deactivating the multi-viewpoint light beams along a periphery of the cylindrical light-emitting array in a rotational direction; and the cylindrical light-emitting array being formed such that two-dimensional light-emitting-array elements are arranged so as to cover almost an entire periphery of the cylindrical light-emitting array.
