ABSTRACT:
Disclosed is a liquid crystal cell having contiguous to a surface of a constraint thereof one or more compensator layers, each containing a transparent amorphous polymeric birefringent material having an out-of plane birefringence more negative than −0.005. The invention also provides a liquid crystal display and a process for making such a cell.
