CHOLESTERIC LIQUID CRYSTAL DISPLAY THAT PREVENTS IMAGE STICKING

摘要

A liquid crystal material for a display device includes a liquid crystal material comprising first chiral nematic liquid crystal component and a second component that exhibits no liquid crystalline phase. The second component is present in an amount not greater than 5 % by weight based upon the total weight of the liquid crystal display material and is effective to avoid image sticking of the display device when in use. The liquid crystal material has positive dielectric anisotropy. The second component may have a molecular weight not exceeding 205 grams/mole.
