Method for the manufacturing of homeotropically aligned layer of discotic liquid crystals

摘要

The present invention relates to a method for the manufacturing of an homeotropically aligned layer of discotic liquid crystals comprising the steps of:- depositing a layer of a discotic material on a substrate;- depositing a sacrificial layer on said discotic layer;- inducing the homeotropic alignment of the discotic material of the layer by a magnetic field or by thermal annealing;- removing the sacrificial layer.
