摘要： An optical sheet has a large number of cylindrical lens elements provided successively on one of principal faces thereof. The cylindrical lens elements have a hyperboloidal face or a paraboloidal face and have a finite focal distance on the emission side of illumination light. Where a Z axis is taken in parallel to a normal line direction to the optical sheet and an X axis is taken in a direction of the row of the cylindrical lens elements, a cross sectional shape of the cylindrical lens elements satisfies Z=X2/(R+√{square root over ( )}(R2−(1+K)X2)) (where R is the radius of curvature of a distal end vertex, and K is a conic constant).

摘要： A method of manufacturing the optical sheet is provided. The method includes: a first step of heating a composition containing a liquid crystal monomer or liquid crystal prepolymer and a photopolymerization initiator at a temperature equal to or higher than a melting point of the liquid crystal monomer or liquid crystal prepolymer and pressing the composition in a state where the composition is held between a master including a plurality of solid structures disposed continuously in one surface and having shape anisotropy in the one surface and a light transmission film disposed so as to face the solid structures of the master. The method also includes a second step of irradiating the composition with ultraviolet rays at a temperature lower than a phase transmission temperature to an isotropic phase to polymerize the liquid crystal monomer or liquid crystal prepolymer and, after that, separating the light transmission film from the master.
