To provide a light-diffusing layered resin film the surface of which is made smooth and which is reduced in unevenness, and to provide a method for forming the light-diffusing layered resin film, and an antiglare film, antiglare polarizing plate and image display each employing the light-diffusing layered resin film.
The light-diffusing layered resin film comprises a resin layer (A) comprising a transparent resin containing a light diffuser dispersed therein having a 1-20 m weight-average particle diameter and a transparent resin layer (B) superposed on each side of the resin layer (A) and has a 30-500 m thickness. The resin layer (A) has a thickness which is 5-50%, excluding 50%, of the thickness of the light-diffusing layered resin film. The light-diffusing layered resin film is formed in such a manner that a layered film is formed by coextrusion molding while keeping at least one side of the layered film in contact with an elastic roll. The method for forming the light-diffusing layered resin film, and the antiglare film, antiglare polarizing plate and image display each employing the light-diffusing layered resin film are provided.
