ABSTRACT:
Methods for producing a multi-domain alignment layer, as well as the multi-domain alignment layers produced thereby and liquid crystal displays comprising the same, are provided. In the subject methods, a surface of an alignment film, usually present on a substrate such a planar component of a polarized material, is bombarded with ions initially at normal incidence in the presence of an electric field in a manner sufficient such that the ions contact the surface of the alignment film at non-normal incidence. In a preferred embodiment, the electric field is produced by an array of conducting means associated with the surface of the alignment film, at least two of which means are differentially biased, e.g. alternately biased. The resultant alignment layers find use in liquid crystal display devices.
