Abstract
An anti-Newton ring sheet includes an anti-Newton ring layer containing binder resin and particles, and formed on at least one surface of a transparent polymer film, wherein the particles are monodisperse spherical particles having a mean particle diameter of not less than 0.4 μm and not more than 2.0 μm and are contained in an amount of not less than 0.5 parts by weight and not more than 3 parts by weight based on 100 parts by weight of the binder resin. The anti-Newton ring sheet can prevent scratching of a contact surface even if it is brought into contact with a light guide plate or the like made of a softer material, without loss of the anti-Newton ring effect. The anti-Newton ring sheet can be utilized for an optical film having an anti-Newton ring effect by providing an optical function layer such as a light diffusing layer on the surface opposite the anti-Newton ring layer.
