A process for aligning a layer of a liquid-crystalline, polymeric material in which a gas or liquid stream is passed over the liquid-crystalline, polymeric material, preferably for aligning main-chain polymers which have a nematic phase by passing a hot stream of air onto the material. Electrooptical displays which contain an alignment layer of this type have high contrast. The alignment layers have advantages over conventional rubbed alignment layers since, for example, no electrostatic charging takes place. |
