Patent ID: 8345202

Claim:
An antiglare film comprising: a transparent substrate; and an antiglare layer formed on the transparent substrate, the antiglare layer having a concave-convex structure on one side thereof, which side is opposite the side at which the antiglare layer is formed on the transparent substrate, wherein the antiglare layer includes a binder matrix and acrylic-styrene copolymer particles, the binder matrix including an acrylic material having a hydroxyl group, and wherein a quotient R A /H is within a range of 0.30 to 0.80, the quotient R A /H being obtained by dividing the average diameter R A of the acrylic-styrene copolymer particles by the average thickness H of the antiglare layer, and a product |n A −n M |×w A ×H is within a range of 0.70 to 3.00, the product |n A −n M |×w A ×H being the product of: the absolute value |n A −n M | obtained by subtracting the average refractive index n M of the binder matrix from the refractive index n A of the acrylic-styrene copolymer particles; the content w A of the acrylic-styrene copolymer particles when the content w M of the binder matrix in the antiglare layer is 100 parts by weight; and the average thickness H of the antiglare layer, and wherein the absolute value |n A −n M | is not larger than 0.015.
