A liquid-crystal composition which has been designed using elastic constants so as to have an improved light transmittance and which has a negative value of dielectric anisotropy (Δε); a liquid-crystal display element including the liquid-crystal composition; and the liquid-crystal display.nThe liquid-crystal composition has a negative value of dielectric anisotropy (Δε) and has a Г value of 0.28 or less, which is determined using the following equation (2) from: a value of twist elastic constant (K 22 ) determined using the following equation (1) from measured values of dielectric anisotropy (Δε), threshold voltage (Vth), bend elastic constant (K 33 ), dielectric constant of vacuum (ε 0 ), cell gap (d), and spiral pitch (P 0 ); and measured values of splay elastic constant (K 11 ) and bend elastic constant (K 33 ). The liquid-crystal display element includes the liquid-crystal composition. The liquid-crystal display is equipped with the liquid-crystal display element. |
