A new bi‐directional alignment surface is developed. Such alignment surface can be used to control the backflow direction of the liquid crystal. Base on this new alignment layer, a bistable twisted nematic LCD which switches between U and T states without surface anchoring energy breaking has been fabricated successfully.
