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 RA/H, which is obtained by dividing the average diameter RA of 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 |nA−nM|×wA×H, which is the product of: the absolute value |nA−nM| obtained by subtracting the average refractive index nM of the binder matrix from the refractive index nA of the acrylic-styrene copolymer particles; the content wA of the acrylic-styrene copolymer particles when the content wM of 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.
