Abstract

We have studied a novel vertical alignment liquid crystal cell. At initial state of a cell with rubbed parallel on top and bottom substrates, the vertically aligned LCs are twisted by $180^{\circ}$. However, after a critical voltage is applied to the cell, the configuration of the LC changes to optically compensated splay form, where the mid-director lies parallel to the substrate and thus the LC has two hybrid alignments around center.
