To provide a display which can improve viewing angle dependency of a contrast ratio at least in a specific azimuth without design change of a basic structure of a display element, limitation to white display state or black display state, and deterioration in display quality in other directions. The above-mentioned display is a display comprising: a display element with a contrast ratio dependent on a viewing angle; and an anisotropic scattering film having an anisotropic scattering layer, wherein the anisotropic scattering film is located on a viewing screen side of the display element and has a scattering central axis in substantially the same azimuth as an azimuth in which a contrast ratio of the display element in a direction inclined by a certain angle from a normal direction of a viewing screen of the display element has an extreme value.

The present invention provides a Fresnel lens sheet capable of successfully avoiding the 'collapse', 'abrasion' and &#x201c;moir&#xe9;&#x201d; 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 &#x3bc;m.
