Abstract:
The liquid crystal display element uses a liquid crystal composition which has a negative value of dielectric anisotropy (Δε) and is designed to improve light transmittance adjusting an elastic constant, and a liquid crystal display including the liquid crystal display element. The liquid crystal display element uses a liquid crystal composition having a dielectric anistropy (Δε) of less than −1.5, in which a value of Γ of the liquid crystal composition is 0.3 or less, and the value of Γ is obtained from Equation (2) using measured values of a splay elastic constant (K 11 ) and a bend elastic constant (K 33 ) of the liquid crystal composition and a twist elastic constant (K 22 ) value obtained from Equation (1) using measured values of a threshold voltage (Vth), a bend elastic constant (K 33 ), vacuum permittivity (ε 0 ), a cell gap (d), and a helical pitch (P 0 ).
