Encapsulated liquid crystal in liquid crystal material where one liquid crystal has positive birefringence and dielectric anisotropy, the other has only one positive of birefringence and dielectric anisotropy

摘要

A liquid crystal display comprises transparent electrodes formed on opposite surfaces of a pair of transparent substrates and a liquid crystal layer filled between the transparent substrate, in which the liquid crystal layer is formed of at least two kinds of liquid crystals which are separated each other and provided in the form of a layer in the direction horizontal to the substrate, a first kind of liquid crystal includes at least one kind of liquid crystal (liquid crystal I) showing that dielectric constant anisotropy DELTA epsilon >0 and refractive index anisotropy DELTA n>0 and a second kind of liquid crystal includes at least one kind of liquid crystal (liquid crystal II) showing that the dielectric constant anisotropy DELTA epsilon <0 and the refractive index anisotropy DELTA n>0 or liquid crystal (liquid crystal III) showing that the dielectric constant anisotropy DELTA epsilon >0 and the refractive index anisotropy DELTA n<0.
