Provided is a liquid-crystal composition which has at least one of properties including a high nematic-phase upper-limit temperature, a low nematic-phase lower-limit temperature, a low viscosity, adequate optical anisotropy, large dielectric anisotropy, a high resistivity, and high stability to ultraviolet rays and heat or has an adequate balance between at least two of the properties. Also provided is an AM element having a short response time, a high voltage retention, a high contrast ratio, a long service life, etc.nThe liquid-crystal composition comprises a specific compound having a large positive value of dielectric anisotropy as a first component and a specific compound having a low viscosity as a second component, may further contain a specific compound having a high upper-limit temperature or a low viscosity as a third component, a specific compound having a large positive value of dielectric anisotropy as a fourth component, or a specific compound having a negative value of dielectric anisotropy as a fifth component, and has a nematic phase. The liquid-crystal display element includes this composition. |
