1. A lenticular lens screen comprising:

  • a substantially planar screen body;

    a first lenticular lens array formed on a first side of said screen body upon which light beams are incident, said first array comprising a plurality of lenticles, said lenticles each having a cross sectional shape, in a plane perpendicular to a plane of said screen body, which corresponds to an entire or arcuate portion of a semicircle; and

    a second lenticular lens array formed on a second side of said screen body, opposite said first side, from which said light beams are transmitted, said second array comprising a plurality of lenticles, said lenticles each having a cross sectional shape, in a plane perpendicular to a plane of said screen body, which corresponds to an entire or arcuate portion of a semicircle;

    wherein a radius of the lenticles in the first array is greater than a radius of the lenticles in the second array, and an apex of the lenticles in the second array is inwardly spaced, in a plane parallel to a plane of said screen body, from an intersecting point of light beams projected through the lenticles in the first array, in both end portions of said lenticles, in a direction parallel to an optical axis of said lenticles.
