Materials for inducing alignment in liquid crystals and liquid crystal displays

摘要

The present invention provides novel aromatic diamines useful in preparing polyimides for optical alignment layers in liquid crystal displays. The novel compositions comprise side-chains general formula Iwherein D comprises 1 to 4 carbon-carbon double bonds, Cf is a monovalent C4 to C20 fluorocarbon radical and L1 and L2 are linking groups.
