PURPOSE:To obtain a lens sheet having excellent optical characteristics without deviation of the axis in which the lenticular lens pattern of a lens mold is accurately transferred and a lens layer of uniform thickness is formed. CONSTITUTION:This lens sheet consists of a first lens member and a second lens member. The first lens member has a first lens part produced by hardening a hardening type resin compsn. containing a thermoplastic polymer, compd. having one or more unsatd. double bonds in the molecule, and radical polymn. initiator on the one surface of a first sheet-type transparent base body. The second lens member has a second lens part produced by hardening a hardening resin compsn. containing a thermoplastic polymer, compd. having one or more unsatd. double bonds in the molecule, and radical polynm. initiator on the one surface of a second sheet-type transparent base body. These members are laminated with an adhesive layer 4 into one body in such a manner that the first lens part and the second lens part are arranged as the outermost layers. |
