Patent number: 8325418Abstract: An anti-glare film is provided and includes micro concave/convex portions on a surface. An average interval between the micro concave and convex portions is equal to 300 ?m or less. A differentiation with respect to angle d{Log(I(?))}/d? of a logarithm intensity of reflection Log(I(?)) in a direction of a deviation angle ? from a direction of specular reflection has an extreme value. A differentiation d{Log(P(?)}/d? of a histogram P(?) to an inclination angle ? of the micro concave/convex portions has an extreme value. In the anti-glare film 1, a value C(2.0) of transmitted image clarity measured by using an optical comb of a comb width of 2 mm in accordance with JIS-K7105 is equal to 30% or more, and a ratio C(0.125)/C(2.0) of the value C(2.0) measured by using the optical comb of the comb width of 2 mm and a value C(0.125) measured by using an optical comb having a comb width of 0.125 mm is equal to 0.1 or more.Type: GrantFiled: June 20, 2008Date of Patent: December 4, 2012Assignee: Sony CorporationInventors: Tsutomu Nagahama, Yumi Haga, Hitoshi Watanabe, Shinichi Matsumura
