发明名称 Ferroelectric liquid crystal composition and ferroelectric liquid crystal display device.
摘要 <p>Characteristics of a ferroelectric liquid crystal show that ionic impurities deteriorate its display quality to great extent. Thus 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.</p>
