Abstract

A liquid crystal display cell is includes a first substrate; a second substrate; a liquid crystal layer of liquid crystal molecules disposed between the first substrate and the second substrate; a first alignment layer disposed between the first substrate and the liquid crystal layer; and a second alignment layer disposed between the second substrate and the liquid crystal layer; wherein a surface of at least one alignment layer is bombarded by a particle beam of an adjustable energy using a voltage less than 200 V so that the liquid crystal molecules proximate the surface are induced to a predetermined pretilt angle.
