摘要： An anti-glare film has a plurality of diffuser elements, and has specified optical properties. The ratio of I(α+1)/I(α) is more than 0.1 to 0.6, where I(α) is an intensity of a light reflected toward an arbitrary angle α of 10° or less from a specular reflection direction of an incident light upon the surface at an angle of 5° to 30° from the surface normal, and I(α+1) is an intensity of a reflected light deviated from the arbitrary angle α by 1° in a wide-angle direction. The gain of a light reflected in the direction at 20° or more from the specular reflection direction of the incident light is 0.02 or less, in which the gain is obtained by normalizing a reflected light intensity using a specular reflection intensity of a standard diffuse plate as 1. The diffuser elements have an average space therebetween of 50 to 300 micrometers.

摘要： 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 μm or less. A differentiation with respect to angle d{Log(I(α))}/dα of a logarithm intensity of reflection Log(I(α)) in a direction of a deviation angle α from a direction of specular reflection has an extreme value. A differentiation d{Log(P(β)}/dβ of a histogram P(β) to an inclination angle β 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.

摘要： A method for producing an anti-glare film includes applying a coating composition including at least a resin, a solvent, and fine particles to a substrate; drying the coating composition applied to the substrate so that a Benard cell structure is formed in the surface of the coating layer due to convection caused during volatilization of the solvent; and curing the resin contained in the coating composition having formed therein a Benard cell structure to form an anti-glare layer having fine irregularities with a moderate surface waviness. The anti-glare layer has a degree of white muddiness of 1.7 or less, as measured by quantitatively determining a diffuse reflection component of the diffused light incident upon the surface of the anti-glare layer.
