Abstract
An anti-glare film is attached on a surface of a display, and includes an anti-glare layer. The anti-glare layer is set to have a sparkle value of 10 or less, which is defined based on a value of a standard deviation of luminance distribution of the display under a state in which the anti-glare film is attached on the surface of the display, a value of specular gloss of 40% or less, which is measured with 60-degree specular gloss, and a value of transmission image clarity of 40% or less, which has an optical comb of 0.5 mm. Consequently, satisfactory anti-glare property can be provided while appropriately suppressing sparkle on the display.
