Estimating the term…
The invention relates to an alignment layer comprising a polymerized liquid crystal material with homeotrophic orientation, to methods of its preparation, to polymerizable liquid crystal compositions and liquid crystal polymers used for the preparation of the alignment layer, to liquid crystal devices comprising the alignment layer, and to a method of controlling the electrooptical steepness of a liquid crystal display comprising at least one alignment layer by varying the surface anchoring energy of the alignment layer.
An alignment layer comprising a polymerized liquid crystal material with homeotropic orientation, in conjunction with a liquid crystal medium, whereby said layer functions to impart homeotropic alignment to said medium.
