PURPOSE: To obtain a spectacles-less 3D display type stereoscopic picture reproducing device in which a crosstalk is not generated and which does not make a reverse stereoscopic viewing generate and is excellent in the separating of parallatic pictures. CONSTITUTION: An opening pattern 7 in which plural openings 8 are arranged in the horizontal direction is lighten by a lighting means 4 and the plural openings 8 are superposed at finite distance to be formed as a first exit pupil 8R' by a cylindrical lens array 2 constituted by arranging plural cylindrical lenses provided corresponding to plural openings 8 and also a parallatic picture to be displayed on a space light modulator SLM provided in the vicinity of the cylindrical lens array 2 is lighten by luminous flux from the openings 8 and when the parallatic picture is changed to another parallatic picture, the positions of plural openings 8 are changed in synchronization with this and images of plural openings 8 are superposed at the position different from that of the first exit pupil 8R' to be formed as a second exit pupil. Then, the parallatic picture is observed from the first and the second exit pupil positions by periodically repeating these operations. |
