ABSTRACT:
Characteristics of a ferroelectric liquid crystal show that ionic impurities deteriorate its display quality to a great extent. The present invention provides a ferroelectric liquid crystal display device of good display quality without the deterioration of display characteristics, as a result of trapping the ionic impurities effectively by adding an organic material which traps ions and which lowers conductivity of a liquid crystal layer thereto.
