We propose and demonstrate a nano‐structured alignment layer which is capable of producing pretilt angles of any value from 0° to 90°. This alignment layer is robust, stable, reliable and highly manufacturable. We utilized these alignment layers to obtain ∼45° pretilt angles to make a pi‐cell which is in the bend alignment with no bias voltage. This No‐bias bend (NBB) cell has a total response time of <2ms. We have also applied this method to fabricate a bistable bend‐splay display successfully.
