, (2008/06/13)
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 W1 and W2 each independently represents fluorine, chlorine, -CF3, -CF2H, -OCF3, or -OCF2H) and has negative dielectric anistropy.
