METHOD OF MANUFACTURING RETARDATION COMPENSATION FILM, RETARDATION COMPENSATION FILM, COMPOSITE POLARIZING PLATE, POLARIZING PLATE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a retardation compensation film having sufficient retardation and biaxial property as an optical compensation member and having high durability under heating conditions.

SOLUTION: The method of manufacturing the retardation compensation film includes: a heat-drawing step of drawing a film obtained by using an amorphous resin and a thermoplastic elastomer resin that substantially has a phase separation form with respect to the amorphous resin, in at least one of longitudinal and lateral direction while heating; and a heat treatment step of heat-treating the stretched film. In the heat-drawing step, expressions (1): 50<ε/k<500 and (2): TgCOPYRIGHT: (C)2011,JPO&INPIT
