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.
