Optimum optical properties in liquid crystal devices depend on uniform alignment of the molecules within the cell. By merely rubbing a substrate upon which a liquid crystalline material is to reside, non-precise alignment is achieved. Improved alignment has been provided by the use of surface coated chern-ical surfactants and silicone monoxide films vacuum deposited in an oblique fashion onto the substrate.
