<P>PROBLEM TO BE SOLVED: To provide an optical film capable of obtaining high glare-proofness and high contrast, without using a fine particle. <P>SOLUTION: This optical film is provided with a base material with protrusion-shaped structures arranged two-dimensionally and regularly on a surface, and a hardcoat layer formed on a face arranged with the structure of the base material. A continuous corrugated face is formed following the structure of the base material surface, on the hardcoat layer surface, the maximum amplitude A and the minimum wavelength λ of the continuous corrugated face are substantially constant, and a ration (A/λ) of the maximum amplitude A to the minimum wavelength λ is more than 0.002 and 0.011 or less. <P>COPYRIGHT: (C)2010,JPO&INPIT |
