An antiglare film producing method of film productionnby surface embossing to polymer film (11a, 11b) isnprovided. The polymer film includes a support (31, 41) ofntriacetyl cellulose, and an anti-reflection layer (32, 44,n50, 55) overlaid thereon. An embossing roller (22) is usednfor surface embossing to a front surface of the support orna surface of the anti-reflection layer. In the filmnproducing method, the embossing roller is producednaccording to electrodischarge machining (EDM). A surfacenof the embossing roller has an arithmetic average roughnessnRa of 0.3-1.0 micron, and has a protruding and retreatingnpattern with an average cycle length RSm of 5-30 microns. |
