Abstract
A method of collective orientation of the molecules of a mesomorphous liquid crystal, in which each of two oppositely-facing walls of a liquid-crystal cell is covered with a conductive deposit forming an electrode and with a thin film of a substance which exhibits properties of orientation of smectic crystals in solid phase; the mesomorphous liquid crystal is placed in contact with the two thin films and the molecules of said liquid crystal are aligned with those of the thin film.
