Abstract
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.
