Abstract
The present invention provides novel hybrid polymer optical alignment layers for inducing alignment of a liquid crystal medium. Hybrid polymers of this invention comprise at least one component of a macromonomer or polymer within the class of polyimide, polyamic acids and esters thereof, and at least one additional component from the group consisting of an addition monomer, monomers and addition polymer that are covalently bonded with the first component to form a copolymer. The invention further describes liquid crystal displays comprising the novel branched hybrid polymer optical alignment layers.
