MULTILAYERED OPTICAL COMPENSATOR |
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 (Dnth) 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 20nm and the out-of-plane retardation (Rth) of the multilayer compensator is more negative than-20nm or more positive than +20nm. 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. ® KIPO & WIPO 2008 |
