A method for improving the anchoring of liquid crystals on carbon alignment layers used in liquid crystal displays involves exposing the alignment layer to hydrogen atoms. The atomic hydrogen exposure passivates the surface of the carbon layer to stabilize the anchoring of the subsequently deposited liquid crystals. The substrate on which the carbon layer is supported is located beneath a stretched tungsten filament, and the substrate and filament are located in a vacuum chamber containing hydrogen gas. The heating of the tungsten filament by an appropriate power source dissociates the hydrogen gas into hydrogen atoms and the hydrogen atoms contact the surface of the carbon layer. The process is applicable to stabilize carbon alignment layers that have been formed by directional deposition of carbon, as well as carbon alignment layers where the alignment is caused by a separate ion irradiation step after the carbon layer is formed.
