CYCLOOLEFIN RESIN FILM, AND POLARIZATION PLATE, OPTICAL COMPENSATION FILM, ANTIREFLECTING FILM USING THE RESIN FILM, AND LIQUID CRYSTAL DISPLAY DEVICE USING THOSE

摘要

PPROBLEM TO BE SOLVED: To provide a manufacturing method of a norbornene film solving the problem of the non-fused matter accompanied by the non-uniformity of the temperature of a raw material pellet. PSOLUTION: In the method for manufacturing the cycloolefin resin film by a melt extrusion method for heating and melting a cycloolefin resin using a molding machine having a screw to extrude the molten cycloolefin resin, the temperature of a raw material resin at the time when charging of the raw material resin in a screw supply part is set to Tg-80C to Tg+10C and the temperature distribution of the raw material resin is set to a range of 0.5 to 5C.
