Mesogenic polymer network in low molecular weight cholesteric material

摘要

The invention relates to a liquid crystalline material in the form of an anisotropic gel consisting of a polymerized monotropic or enantiotropic liquid crystalline material (a) and a low-molecular weight liquid crystalline material (b), wherein the polymerized material (a) forms a permanently oriented network in the low-molecular liquid crystalline material (b), characterized in that the low-molecular weight liquid crystalline material (b) exhibits a cholesteric phase; and to a display cell with such a material. Various liquid crystalline media are also claimed.
