Optical Retardation Film and Method of Production Thereof

摘要

The present invention relates generally to the field of organic chemistry and particularly to the optical retardation films for liquid crystal displays. The present invention provides an optical film comprising a substrate having front and rear surfaces, and at least one solid retardation layer on the front surface of the substrate. Said solid retardation layer comprises rigid rod-like macromolecules comprising n organic units of the first type having general structural formula I and k organic units of the second type having general structural formula II
