A liquid crystal composition is described, which satisfies at least one characteristic among high maximum temperature of a nematic phase, low minimum temperature of a nematic phase, small viscosity, large optical anisotropy, large dielectric anisotropy, large specific resistance, high stability to ultraviolet light, high stability to heat and so on, or is properly balanced regarding at least two of the characteristics. To provide an AM device having short response time, large voltage holding ratio, large contrast ratio, long service life and so forth, the liquid crystal composition has a nematic phase and contains a specific three-ring compound having a large optical anisotropy as a first component, a specific four-ring compound having a large dielectric anisotropy as a second component, and a specific two-ring compound having a particularly small viscosity as a third component. A liquid crystal display device containing the liquid crystal composition is also described.
A liquid crystal composition having a nematic phase, including a first component as at least one compound selected from the group of compounds represented by formula (I-1) and formula (I-2), a second component as at least one compound selected from the group of compounds represented by formula (2), and a third component as at least one compound selected from the group of compounds represented by formula (3):
