Title: (EN) Multilayer optical compensator
(ZH) 多层光学补偿器
Abstract: front page image
(EN) 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.
(ZH)

一种包含一或多个聚合第一层和一或多个聚合第二层的多层补偿器。所述第一层包含一种面外(Dnth)双折射率不小于-0.01且不大于+0.01的聚合物。所述第二层包含一种面外双折射率小于-0.01或大于+0.01的无定形聚合物。多层补偿器的总面内延迟(Rin)大于20nm,且多层补偿器的总面外延迟(Rth)小于-20nm或者大于+20nm。所述一或多个第一层的面内延迟(Rin)是多层补偿器总面内延迟(Rin)的30%或更小。
