Liquid crystal device |
摘要 |
A liquid crystal device which comprises a pair of substrates having an electrode layer, at least one of said substrates being transparent, and a light-control layer supported between the substrate is disclosed, wherein said light-control layer comprises a continuous liquid crystal phase composed of a nematic liquid crystal material and a transparent solid substance having the three dimensional network existing in said continuous liquid crystal phase, said nematic liquid crystal material having an optical anisotropy ( DELTA n) ranging from 0.18 to 0.3 and a dielectric anisotropy ( DELTA epsilon ) ranging from 15 to 30. The device can be driven at a low voltage to provide a display of sufficient contrast and is applicable to a multiplexing drive system.
