Abstract
The invention relates to a method for the production of orientation layers for liquid crystal displays by applying a solution of an organic prepolymer to a transparent substrate and subsequently annealing the layer and subjecting it to an orientation treatment, wherein prepolymers of polyoxazoles, polythiazoles, polyimidazoles, polyoxazinones, polyoxazine diones or polyquinoxalines are used as the organic prepolymer. The method is particularly suitable for the preparation of orientation layers for glass-solder liquid crystal displays.
