Liquid crystal display device

A liquid crystal display device that has an FFS mode as an operating mode of the liquid crystal display device and an active matrix mode as a driving mode thereof, and contains a liquid crystal composition having a positive dielectric anisotropy, wherein the liquid crystal composition contains at least one compound selected from the group of compounds represented by formula (1) as a first component, at least one compound selected from the group of compounds represented by formula (2) as a second component, and at least one compound selected from the group of compounds represented by formula (3-1) and formula (3-2) as a third component, wherein at least one of the third component is a compound selected from a group of compounds represented by formula (3-2), and a ratio of the first component is 10% by weight or more based on the total weight of the liquid crystal composition:
