METHOD FOR MANUFACTURING ALICYCLIC POLYOLEFIN RESIN FILM, ALICYCLIC POLYOLEFIN RESIN FILM, ALICYCLIC POLYOLEFIN RESIN FILM FOR BASE FOR LIQUID CRYSTAL DISPLAYING ELEMENT, AND BASE FOR LIQUID CRYSTAL DISPLAYING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing an alicyclic polyolefin resin film which can be used as a base for a liquid crystal displaying element with excellent optical characteristics. SOLUTION: In the method for manufacturing the alicyclic polyolefin resin film in which an alicyclic polyolefin resin is melted and is made into a film by means of a melt extrusion method, the method for manufacturing the alicyclic polyolefin resin film is characterized by performing vacuum drying of the alicyclic polyolefin resin before it is melted and in this case, the vacuum drying is preferably performed at a temperature of at least 100 deg.C and under a pressure of lower than 100 mmHg.
