<p>PROBLEM TO BE SOLVED: To provide a screen having a structure that is less susceptible to denting of apex portions even when the screens having concavo-convex surfaces are stacked.SOLUTION: A screen includes a light-transmissive substrate 11 and a unit optical element 13 provided on one surface side of the substrate and having a concavo-convex pattern that forms apexes 13c. The unit optical element is made of a cured product of an active energy ray-curable resin composition containing an acrylate resin and/or a methacrylate resin, and has an elastic modulus of 2300 MPa or more. When a load applied to the apexes of the unit optical element is varied from 0 mN to 200 mN at a constant pace, kept at 200 mN for 60 seconds upon reach 200 mN, and then reduced to 0.4 mN to be kept there for 4 seconds, in accordance with the Vickers hardness test specified in JIS Z2244(2003), a recovery rate of the apexes with respect to a pre-loading state thereof is 40% or more.</p> |
