Abstract:
1. A liquid crystal display device using nematic liquid crystal material, comprising: (a) a pair of substrates, at least one of the substrates being transparent; (b) plate-like electrode layers formed on surface of the pair of substrates respectively, at least one of the plate-like electrode layers being transparent; (c) a liquid crystal layer interposed between said pair of substrates, wherein an electric field is imposed therethrough by applying a voltage on the plate-like electrode layers; and (d) an alignment layer arranged between the liquid crystal layer and at least one substrate of the pair of substrates, the alignment layer comprising alignment domains processed for the liquid crystal anchoring treatment in a plurality of different directions including a substantially vertical and a substantially horizontal direction to the surface of the substrate, (e) wherein the liquid crystal display device has two liquid crystal orientation states both formed in a checker board like pattern of a substantially vertical orientation state and a substantially horizontal orientation state to the surface of the substrate, each state being stable and having a memory characteristic in the absence of the electric field.
