<P>PROBLEM TO BE SOLVED: To provide a new method for manufacturing a lens film. <P>SOLUTION: In the inventive method for manufacturing a lens film with a surface on which a lens array layer having a fine rugged shape is laminated, a multilayer film in which a first resin layer, a second resin layer having a phase transition temperature lower than that of the first resin layer, and a third resin layer having a phase transition temperature higher than that of the first resin layer are laminated in this order is subjected to free-end uniaxial stretching at a stretching temperature which is higher than the phase transition temperature of the second resin layer, thereby forming the lens array layer having a fine rugged shape on the surface of the first resin layer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
