Subject The subject is to provide a liquid crystal display device having characteristics such as a short response time, a large voltage holding ratio, a low threshold voltage, a large contrast ratio, a long service life and a small flicker rate. Means for solution The means concerns a liquid crystal display device including a first substrate, a second substrate and a liquid crystal composition having positive dielectric anisotropy, which is placed between these substrates, wherein the liquid crystal composition has a nematic phase and includes at least one compound selected from the group of compounds represented by formula (1) as a first component:
in formula (1), R 1 is alkyl or the like; ring A is 1,4-phenylene or the like; Z 1 is a single bond or the like; X 1 and X 2 is hydrogen or fluorine; Y 1 is fluorine or the like; and m is 0, 1, 2, 3 or 4. |
