Abstract

A process for producing thin, anisotropic layers composed of liquid crystalline substances, the liquid crystalline substances being applied in a thin layer to one side of a support having a surface prestructured in such a way that the structure is given a preferred direction which determines orientation of the liquid crystalline substance and data storage devices produced.
