Abstract: An antiglare film includes, in order: a substrate; a first layer; and a second layer with an uneven structure including elongated projection portions on a surface opposite to a substrate side and an arithmetic mean height Sa on that side of the substrate is 30 to 160 nm, an average distance between adjacent elongated projection portions is 5 to 80 μm, a content of particles having a particle diameter of 300 nm or more in the second layer is 0% to 0.1% by mass with respect to a total mass of the second layer, an average film thickness of the second layer is 0.3 to 3 μm, a haze of the antiglare film is 1% to 20%, and where a surface of the antiglare film on the opposite to the substrate side is rubbed 100 times with #0000 steel wool under a load of 1 kg/cm2, no scratch occurs.

Abstract: An optical film includes a base material film including a (meth)acrylic resin and a first cured layer obtained by curing a first composition including a curable compound, in which the first cured layer is formed of a compatible layer and a first hardcoat layer, the compatible layer and the first hardcoat layer are provided in this order from the base material film side, and a pencil hardness of a surface of the optical film on the first cured layer side is H or more, and a peak intensity value of a power spectrum obtained by means of Fourier transformation of a reflectivity spectrum measured from the first cured layer side of the optical film by means of an optical interference-type non-contact surface shape measurement is 0.001 to 0.030. A method for manufacturing an optical film and an image display device includes the optical film.
