An apparatus ( 10, 10'' ) for producing an alignment surface on an associated substrate ( 12, 12'' ) of a liquid crystal display. An electron source ( 40 ) produces a collimated electron beam ( 50 ). A substrate support ( 20, 20'' ) supports the associated substrate ( 12, 12'' ) with a surface normal ( 80 ) of the substrate arranged at a preselected angle (alpha) relative to the collimated electron beam ( 50 ). The collimated electron beam ( 50 ) is rastered across the associated substrate ( 12, 12'' ) at the preselected angle (alpha) while the substrate moves through the electron beam.
