    摘要: A multilayer compensator includes one or more polymeric first layers and one or more polymeric second layers. The first layers comprise a polymer having an out-of-plane (Δnth) birefringence not more negative than −0.01 and not more positive than +0.01. The second layers comprise an amorphous polymer having an out-of-plane birefringence more negative than −0.01 or more positive than +0.01. An overall in-plane retardation (Rin) of the multilayer compensator is greater than 20 nm and the out-of-plane retardation (Rth) of the multilayer compensator is more negative than −20 nm or more positive than +20 nm. The in-plane retardation (Rin) of the one or more first layers is 30% or less of the overall in-plane retardation (Rin) of the multilayer compensator.
