摘要： 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.
摘要翻译： 铁电液晶的特征表明离子性杂质在很大程度上使其显示质量恶化。 因此，本发明提供了一种具有良好显示质量的铁电液晶显示装置，而不会由于通过添加捕获离子的有机材料和降低其液晶层的导电性而有效地捕获离子杂质而导致显示特性的劣化。
