Project to be solved by this invention is to provide a kind of liquid crystal display element of liquid-crystal composition being negative using dielectric constant anisotropy, the liquid-crystal composition can nematic phase stability, γ 1 etc. when not making dielectric constant anisotropy, viscosity, nematic phase ceiling temperature, low temperature excellent display characteristic is realized and the liquid crystal display element for FFS mode in the case where deteriorate as each characteristic of liquid crystal display element and the burn-in characteristic of display element.The present invention provides a kind of liquid crystal display element, contains at least one of the compound group represented by the following general formula (I) compound, [changing 1] In formula, R 1 And R 2 The alkenyloxy group of the alkyl of carbon atom number 1~8, the alkenyl of carbon atom number 2~8, the alkoxy of carbon atom number 1~8 or carbon atom number 2~8 is each independently represented, A indicates Isosorbide-5-Nitrae-phenylene or anti-form-1,4- cyclohexylidene, k indicates 1 or 2, and when k is 2, two A can be the same or different. |
