Abstract

We studied the liquid crystal (LC) alignment capabilities and the generation of pretilt angles with ion beam exposure on a diamond like carbon (DLC) layer. A high pretilt angle of 3.5$^{\circ}$ with ion beam exposure on the DLC layer can be obtained. A high pretilt angle in NLC by ion beam alignment method on the DLC layer can be achieved.
