Abstract

There is provided an FFS mode liquid crystal display device that uses a liquid crystal composition which has a negative dielectric anisotropy and can achieve good display properties by being used for FFS mode liquid crystal display devices without degrading the image sticking property of display devices and various properties of liquid crystal display devices, such as dielectric anisotropy, viscosity, nematic phase upper limit temperature, low-temperature nematic phase stability, and γ. The liquid crystal composition contains at least one compound selected from the group of compounds represented by general formula (I) below, at least one compound selected from the group of compounds represented by general formula (II) below, and at least one compound selected from the group of compounds represented by general formula (III) below.
