Abstract
An antiglare film includes a transparent substrate, and an antiglare layer formed on the transparent substrate. The antiglare layer includes a binder matrix and acrylic-styrene copolymer particles, and the binder matrix includes an acrylic material having a hydroxyl group. A quotient R/H, which is obtained by dividing the average diameter Rof the acrylic-styrene copolymer particles by the average thickness H of the antiglare layer, is within a range of 0.30 to 0.80. A product in |n−n|×w×H, which is the product of: the absolute value |n−n| obtained by subtracting the average refractive index nof the binder matrix from the refractive index nof the acrylic-styrene copolymer particles; the content wof the acrylic-styrene copolymer particles when the content wof the binder matrix in the antiglare layer is 100 parts by weight; and the average thickness H of the antiglare layer, is within a range of 0.70 to 3.00.
