Abstract

We demonstrate a liquid crystal alignment layer with controllable polar and azimuthal anchoring energies. This alignment layer is based on a nanostructured surface formed by mixing a conventional polyimide and a nonaligning polymer. By using this variable anchoring alignment layer, large cell gap bistable twisted nematic LCD requiring asymmetric anchoring can be fabricated.
