    摘要： An optical film includes a base member and an optical layer provided on the base member. The optical layer has an irregular shape on a surface thereof, and the irregular shape is obtained by applying a coating material containing fine particles and a resin onto the base member, distributing the fine particles densely in some regions and sparsely in other regions by convection that occurs in the coating material, and curing the coating material. The resin contains 3% by weight or more and 20% by weight or less of a polymer, the fine particles are organic fine particles having an average particle diameter of 2 μm or more and 8 μm or less, a ratio ((D/T)×100) of the average particle diameter D of the fine particles to an average film thickness T of the optical layer is 20% or more and 70% or less, and a transmitted image clarity value measured with an optical comb having a width of 0.125 mm is 45 or more.

    摘要： An anti-glare film is provided and includes micro concave/convex portions on a surface. An average interval between the micro concave and convex portions is equal to 300 μm or less. A differentiation with respect to angle d{Log(I(α))}/dα of a logarithm intensity of reflection Log(I(α)) in a direction of a deviation angle α from a direction of specular reflection has an extreme value. A differentiation d{Log(P(β)}/dβ of a histogram P(β) to an inclination angle β of the micro concave/convex portions has an extreme value. In the anti-glare film 1, a value C(2.0) of transmitted image clarity measured by using an optical comb of a comb width of 2 mm in accordance with JIS-K7105 is equal to 30% or more, and a ratio C(0.125)/C(2.0) of the value C(2.0) measured by using the optical comb of the comb width of 2 mm and a value C(0.125) measured by using an optical comb having a comb width of 0.125 mm is equal to 0.1 or more.

    摘要： An optical body includes a first optical layer having a concave-convex surface, a wavelength selective reflecting layer formed on the concave-convex surface, and a second optical layer formed on the wavelength selective reflecting layer and embedding the concave-convex surface. The wavelength selective reflecting layer selectively directionally reflects light in a particular wavelength band while transmitting light other than the particular wavelength band therethrough. The concave-convex surface is made up of a plurality of triangular pillars arrayed in a one-dimensional pattern, and the triangular pillar has an apex angle α and a slope angle β, the apex angle α and the slope angle βsatisfying a predetermined relationship.

    摘要： An anti-glare film has a plurality of diffuser elements, and has specified optical properties. The ratio of I(α+1)/I(α) is more than 0.1 to 0.6, where I(α) is an intensity of a light reflected toward an arbitrary angle α of 10° or less from a specular reflection direction of an incident light upon the surface at an angle of 5° to 30° from the surface normal, and I(α+1) is an intensity of a reflected light deviated from the arbitrary angle α by 1° in a wide-angle direction. The gain of a light reflected in the direction at 20° or more from the specular reflection direction of the incident light is 0.02 or less, in which the gain is obtained by normalizing a reflected light intensity using a specular reflection intensity of a standard diffuse plate as 1. The diffuser elements have an average space therebetween of 50 to 300 micrometers.
