Abstract
A liquid crystal device comprising a pair of substrate, at least one of them being transparent, and a light-control layer supported therebetween, wherein said light-control layer comprises a liquid crystal material showing positive dielectric anisotropy and a transparent solid substance, said liquid crystal material forming a continuous phase, and said transparent solid substance existing in said continuous phase in the form of dispersed particles or a three-dimensional network. The device exhibits a clear threshold voltage, a high fast response time and a highly contrast display with a low applied voltage.
