A transparent layered film is produced by forming an anti-water-mark layer on a first side of a transparent resin layer and forming an uneven structure on a surface of the anti-water-mark layer, wherein the anti-water-mark layer comprises a cured product of a curable composition containing a curable resin, a thermoplastic resin, and a metal oxide particle having an average primary particle size of 1 to 100 nm, and the uneven structure has a roughness average Ra of not less than 0.005 and less than 0.03 &#x3bc;m, a mean spacing of profile irregularities Sm of 50 to 300 &#x3bc;m, an average absolute slope &#x394;a of less than 0.1&#xb0;, and a ten-point average roughness Rz of less than 0.2 &#x3bc;m. Lamination of the film on a glass-containing upper electrode of a touch screen display prevents scattering of glass fragments produced by breakage of the upper electrode, occurrence of water marks, and sparkling on a high-definition display provided with the film.
