ABSTRACT:
A bistable nematic liquid crystal device includes an array of holes (8) in an alignment layer (6) on at least one cell wall (2). The alignment layer (6) induces a substantially planar local alignment of liquid crystal molecules. The holes (8) have a shape and/or orientation to induce the liquid crystal director adjacent the holes (8) to adopt two different tilt angles in substantially the same azimuthal direction. The arrangement is such that two stable liquid crystal molecular configurations can exist after suitable electrical signals have been applied to the electrodes.
