| titleOfInvention | Method for producing three-dimensional birefringent film |
| abstract | PROBLEM TO BE SOLVED: To easily control and retain a refractive index in a plane direction and a thickness direction of a three-dimensional birefringent film used as a viewing angle widening film, and to change an initial retardation value. Provided is a method for producing a three-dimensional birefringent film having a small amount. SOLUTION: A transparent thermoplastic resin film formed by a solution casting method is longitudinally uniaxially stretched in a longitudinal direction at least on one side of a stretched film. A method for producing a three-dimensional birefringent film, wherein the stretched film is heat-shrinked and then stretched to control and hold the molecular group oriented in the plane direction and the molecular group oriented in the thickness direction. The shrinkage ratio A in the horizontal direction of the heat shrinkable film during heat shrinkage is 8 to 25. %, And the contraction rate in the machine direction of the stretched film is (１ ／) ３) A method for producing a three-dimensional birefringent film, characterized by A%. |
