A new kind of nano‐structured alignment surface is proposed and demonstrated. Such alignment surface is capable of generating arbitrary pretilt angles for liquid crystal. The new alignment surface is based on nano‐imprinting and plasma etching. The domain sizes are fixed and controllable; in addition, no random process is involved. The alignment surface is robust and highly reproducible. Moreover, the processing window is maximized and suitable for mass manufacturing.
