PROBLEM TO BE SOLVED: To enable plural stereoscopic pictures to be observed satisfactorily from plural positions by properly setting respective elements such as two lenticular lenses, mask pattern, display respectively dividing plural parallactic pictures into many lateral strip shaped parallactic pictures and displaying the divided plural lateral strip shaped parallactic pictures in the vertical direction with a prescribed pitch and so fourth. SOLUTION: Displayed picture information are observed by passing luminous fluxes through the first lenticular lens 3 of the armament of the horizontal direction and the second lenticular lens 4 of the arrangement of the vertical direction and by lighting a display 6 with the luminous fluxes passed through the lenses. At this time, picture information are displayed in such a manner that N pieces of parallatic picture are respectively divided into many lateral strip shaped parallactic pictures and divided parallatic pictures are arranged in accordance with the N pieces of parallatic pictures to be synthesized. The horizontal direction of a master pattern 9 is constituted of line patterns in which N-1 or N pieces of light shielding part are repeatedly arranged with respect to one opening part and in the vertical direction of the masterpattern, pairs in which N pieces of the lines part are arranged while they are shifted each other by the width of the opening part are arranged in the vertical direction. |
