A linear Fresnel lens sheet includes: a lens layer having a first surface in which a linear Fresnel lens portion, having a number of lens surfaces arranged in a first direction d1, is formed, and a second surface opposite the first surface; and a diffusion layer disposed on the side of the second surface of the lens layer.

A method for manufacturing a printed product comprises provision (210) of a matrix comprising a matrix surface having a plurality of recesses. A first curable compound is applied (212) to the matrix surface to fill the recesses with the compound. The matrix surface and the filled recesses are covered (220) by a pickup layer of a second curable compound. The matrix is brought (230) in contact with the substrate surface and the first curable compound and the second curable compound are cured (232). The matrix surface is separated (234) from the substrate surface, leaving the pickup layer and the first curable compound on the substrate surface. The pickup layer and the first curable compound are thus transferred (240) together from the matrix surface onto a substrate surface of a substrate sheet. The first curable compound forms printed product micro features at the pickup layer covering the substrate surface.

There is provided a new and improved optical body, optical film adhesive body, and method for manufacturing an optical body, in which a concave-convex structure of an optical film can be protected without the use of a protective film, the optical film can be made thinner, the handling properties can be improved, the occurrence of defects caused by a difference in the refractive index between an adhesive layer and the optical film can be minimized, and the optical film can be applied more firmly to the adherend, the optical body including: an optical film provided with first and second concave-convex structures; and a master film in which an average period of concavities and convexities of the first concave-convex structure is less than or equal to visible light wavelengths, and the master film is provided with a third concave-convex structure which has a reverse shape of the first concave-convex structure.
