MULTILAYER OPTICAL FILM

摘要

PROBLEM TO BE SOLVED: To provide an optical film having a small absolute value of thickness-direction retardation (Rth). SOLUTION: The multilayer optical film is obtained by stacking a film A whose thickness-direction retardation (Rth) is positive and a film B whose thickness-direction retardation (Rth) is negative.
