    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 or 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.

    摘要： A multilayer compensator has two or more first layers and one or more second layers. The overall in-plane retardation of the compensator is from 0 to 300 nm and the out-of-plane retardation is more negative than −20 nm or more positive than +20 nm. The compensator may be fabricated by: coating at least one barrier layer on at least one first layer; coating at least one second layer from an organic coating solvent on the barrier layer to produce an intermediate compensator structure; and stretching the intermediate compensator structure in at least one direction by between 1% and 60%. The barrier layer contains a polymer that is water soluble or water dispersible in an amount sufficient to impede the diffusion of the organic solvent between the other first layers and the second layers. All layers have been stretched simultaneously.
