ABSTRACT:
Disclosed is an optical compensator for liquid crystal displays comprising a first polymeric layer having an out-of-plane birefringence not more negative than −0.005 and a second polymeric layer having an out-of-plane birefringence more negative than −0.005. The invention also provides an LC display and a process for making such compensators.
