ABSTRACT:
The invention relates to a method of providing a surface layer on a substrate, which surface layer can bring about an inclined orientation of the molecules of the liquid crystalline layer applied to the surface layer at the interface between the surface layer and the liquid crystalline layer. The surface layer is manufactured from a liquid crystalline auxiliary layer in which the orientation of at least a part of the molecules is permanently fixed.
