Lens sheet.

摘要

A lens sheet comprising a transparent substrate and a lens portion composed of a cured product of an ultraviolet-curable resin composition, which is formed on at least one surface of the transparent substrate. The resin composition exhibits a polymerization shrinkage at curing of not larger than 20% as calculated based on the difference of the specific gravity at 25 DEG C, and a modulus of elasticity at 25 DEG C after curing of 10 to 1,000 kg/cm<2>. The ultraviolet-curable resin composition is preferably comprised of a polyvalent (meth)acrylate, a mono(meth)acrylate and a photopolymerization initiator.
