ABSTRACT:
A multilayer compensator comprising one or more polymeric A layers and one or more polymeric B layers, wherein said A layers comprise a polymer having an out-of-plane birefringence not more negative than −0.01, said B layers comprise an amorphous polymer having an out-of-plane birefringence more negative than −0.01, and the overall in-plane retardation (Rin) of said multilayer compensator is greater than 20 nm and the out-of-plane retardation (Rth) of said multilayer compensator is more negative than −20 nm.
