Wide-view multilayer optical films

摘要

A multilayer optical film includes a wave plate having a refractive index profile of nx>ny≧nz and a fluoropolymer film comprising a moiety of;
wherein R1, R2, and R3 are each independently hydrogen atoms, alkyl groups, substituted alkyl groups, or halogens, wherein at least one of R1, R2, and R3 is a fluorine atom, wherein R is each independently a substituent on the styrenic ring, n is an integer from 0 to 5 representing the number of the substituents on the styrenic ring, and wherein nx and ny represent in-plane refractive indices and nz the thickness-direction refractive index of the wave plates; wherein said multilayer optical film has a positive in-plane retardation (Re) and an out-of-plane retardation (Rth) that satisfies the equation of |Rth|
