PURPOSE: An antiglare film is provided to ensure black brightness, anti-glare, and excellent sparkling and to prepare an excellent optical film with no change of haze and visibility. CONSTITUTION: An antiglare film comprises a transparent substrate and an antiglare coating layer formed on at least one side of the transparent substrate. Spherical particles of the coating layer satisfies the relational expression: 0.7×(4πr^2) <= Sa <= 1.5×(4πr^2), wherein Sa is the surface area of the spherical particle; and r is the radius of the spherical particle. The spherical particle is one of acryl, polystyrene, melamine or silica. |
