Abstract: An optical layered product has a translucent substrate having at least an optically functional layer, containing translucent microparticles, provided directly or via another layer onto one or both sides of the substrate. The standard deviation of area dispersion variability of the translucent microparticles in the optically functional layer is in the range of 0.04 to 0.20.

Abstract: In a composition layering one layer on a transparent substrate, the present invention provides an optical film which can balance anti-glare function, high contrast, color reproducibility, and anti-glittering enough. The optical film in the present invention comprises a transparent substrate, and a resin layer layered on the transparent substrate, the resin layer including transparent resin fine particles and a radiation-curable resin composition, and having a fine rugged structure of an average inclination angle in a range of 0.8° to 3.0° on the top surface of the resin layer; a haze value which is in a range of 40% to 60%; and a transmitted image clarity which is measured by using an optical comb having width of 0.5 mm and is in a range of 5% to 35%.

Abstract: The present invention provides a Fresnel lens sheet capable of successfully avoiding the “collapse”, “abrasion” and “moiré” problems. A Fresnel lens sheet constitutes, together with a lenticular lens sheet, a rear projection screen, which is mounted in the frame of a rear projection type display. The Fresnel lens sheet includes, on one surface of its substrate, a Fresnel lens part containing a plurality of lenses concentrically formed on one plane. The apexes of the lenses situated in the area between the center and the outer edge of the Fresnel lens part are flattened to give flat faces, and the widths of the flat faces of the lenses on the outer edge side are made greater than the widths of the flat faces of the lenses on the center side. The widths of the flat faces of the lenses are from 0 to 30 ?m.
