Abstract
A method of aligning liquid crystals in the construction of liquid crystal cell for use in optical devices is provided. The method involves formation of a self-assembled monolayer on substrates used to form the cells. The substrate having the monolayer are then rubbed in one direction. Two substrates are combined with rubbing directions anti-parallel and spaced to form a cell. A liquid crystal is then inserted and aligned between the substrates. High quality alignment is achieved with this method.
