Abstract
A method for producing a viewing angle compensator includes steps of aligning two substrates, injecting a UV-curable liquid crystal monomer between the two substrates and polymerizing the UV-curable liquid crystal monomer to form a viewing angle compensator for the liquid crystal display. The compensator for a liquid crystal display has a retardation, in the range between 100 and 1000 nm.
