ABSTRACT:
An antiglare film producing method of film production by surface embossing to polymer film is provided. The polymer film includes a support of triacetyl cellulose, and an anti-reflection layer overlaid thereon. An embossing roller is used for surface embossing to a front surface of the support or a surface of the anti-reflection layer. In the film producing method, the embossing roller is produced according to electrodischarge machining (EDM). A surface of the embossing roller has an arithmetic average roughness Ra of 0.3-1.0 micron, and has a protruding and retreating pattern with an average cycle length RSm of 5-30 microns.
