METHOD FOR MANUFACTURING PHASE DIFFERENCE FILM AND METHOD FOR MANUFACTURING LAYERED POLARIZING PLATE

摘要

This method for manufacturing a phase difference film has a step for applying a resin solution on a support body film (1), and a step for heat-drying the resin solution and forming a layered body (2) in which the coating is bonded to and layered on the support body film (1). It is preferable that the method for manufacturing the phase difference film additionally have a step for stretching the layered body (2) in at least one direction and imparting the coating with optical anisotropy, the support body being peeled from the layered body after stretching. The support body film used in this manufacturing method has a tensile modulus of elasticity at 140°C of 200-1200 MPa prior to the application step.
