Abstract: Improved screen for the reproduction of three-dimensional images, static or moving, and a method for manufacturing it. The screen is characterized in that the frames of cylindrical lenses are optically convergent and/or divergent; both frames of cylindrical lenses are formed by cylinders of semi-circular cross-section, juxtaposed in their axial direction, and are arranged on one or both faces of the screen, with the possibility of checking A) that the angle alpha between the two frames is equal to 90.degree., the frame of vertical cylindrical lenses then being covered by a transparent substance with a refractive index n'; or b) that this angle is less than 90.degree.; or c) that this angle alpha is less than 90.degree., and that the frames of cylindrical lenses are covered with a substance with a refractive index n". The method involves: a) preparing a first mould; b) producing a counter-mould; c) producing a final mould; and d) moulding the frames by pressing with the final mould.
