Abstract:
The present invention provides a liquid crystal display device using nematic liquid crystal material with low power consumption and having a memory characteristic which can be easily fabricated with a high yield. The liquid crystal device using nematic liquid crystal material includes: a pair of substrates (1,4) with plate-like electrode layers (2,5) thereon; a liquid crystal layer interposed between the pair of substrates (1,4); and alignment layers (3,6) arranged between the liquid crystal layer and at least one of the pair of substrates (1,4). The alignment layers (3,6) include a plurality of different alignment domains having a substantially vertical direction and substantially horizontal direction to the surface of the substrate. Both of two orientation states, i.e. a substantially vertical orientation state and a substantially horizontal orientation state of the liquid crystal, are stable and have a memory characteristic in the absence of an electric field.
