Claims

[Claims for Utility Model Registration] (1) A first reflector consisting of a transparent synthetic resin film or sheet on which rectangular or hexagonal unit curved surfaces are regularly arranged on a plane and contains a scale-like pearl pigment. a second reflective layer made of a synthetic resin film or sheet having a metallized layer having a curved surface substantially corresponding to the unit curved surface of the first reflective layer; a first backing layer made of a synthetic resin film or sheet; A second backing layer including a fiber reinforcing layer is sequentially laminated and integrated, each side of a unit curved surface of the first reflective layer is 0.5 to 2.0 mm, and the radius of curvature of the curved surface is 0.5 to 2.0 mm. The radius of curvature of the unit curved surface of the second reflective layer is larger than the radius of curvature of the unit curved surface of the first reflective layer, and the boundaries of each adjacent curved surface are continuous curved surfaces, and the radius of curvature is equal to that of the unit curved surface. A reflective screen characterized by a radius of curvature smaller than the radius of curvature. (2) The reflective screen according to claim 1, wherein the first backing layer is made of a white synthetic resin. (3) The reflective screen according to claim 1 or 2, wherein the thickness of the concave portion of the unit curved surface of the first reflective layer is smaller than the thickness of the boundary portion thereof.
