<p>The liquid crystal cell according to the invention is comprised, at least on one of its plates, of an alignment layer consisting of a soluble halogenated polymer of the ethylenic substituted ethylene cycloaliphatic or heterocycloaliphatic type. Such layer induces a homeotropic or planar alignment of crystal molecules in contact with said layer depending on whether the temperature is lower or higher than a predetermined temperature THP.</p> |
