The solid phase-nematic phase transition temperature (Tcn) is sufficiently low without reducing the refractive index anisotropy (Δn) and the nematic phase-isotropic liquid phase transition temperature (Tni), and the viscosity (η). Provides a liquid crystal composition having a sufficiently low rotational viscosity (γ1), a large elastic constant (K33), a large absolute value and a negative dielectric anisotropy (Δε), and has excellent display quality Providing liquid crystal display devices with high response speed. A first component contains a compound represented by general formula (Ia), a second component contains a compound represented by general formula (Ib), , R13 and R14 are a liquid crystal composition having a content of 90 to 100% by mass of a compound which is not an alkenyl group having 2 to 8 carbon atoms. In addition, a liquid crystal display element using the same. [Selection figure] None |
