摘要: A bistable nematic liquid crystal device includes an array of upstanding features ( 10 ) on at least one cell wall 2 ). The have a shape and/or orientation to induce the director adjacent adopt two different tilt angles in substantially same azimuthal direction. arrangement is such that stable molecular configurations can exist after suitable electrical signals been applied electrodes 12, 14
