发明名称 CHROMANDERIVAT UND ES ENTHALTENDE FLÜSSIGKRISTALLINE ZUSAMMENSETZUNG
摘要 The present invention relates to a liquid crystal compound which has negative dielectric anisotropy and a large absolute value thereof; and a liquid crystal display element which contains the compound as a constituent element and has a negative value of dielectric anisotropy in the vertical alignment mode, IPS, or the like. The liquid-crystal display element has a structure including a pair of substrates and a liquid crystal sandwiched therebetween, and includes at least an alignment control layer, a transparent electrode, and a polarizing plate, in which the liquid crystal includes at least one compound having a partial structure represented by general formula (A): (wherein W 1 and W 2 each independently represents fluorine, chlorine, -CF 3 , -CF 2 H, -OCF 3 , or -OCF 2 H) and has negative dielectric anistropy.
