General formula (i), general formula (ii), and general formula (iii) 1 or 2 or more types of compounds chosen from the compound group represented by these, and the following general formula (II) An FFS-type liquid crystal display device containing one or more compounds selected from the compounds represented by formula (1) is provided. The display element is excellent without deteriorating dielectric anisotropy, viscosity, nematic phase upper limit temperature, nematic phase stability at low temperature, various characteristics as a liquid crystal display element such as γ1, and image sticking characteristics of the display element. Display characteristics can be realized. |
