PROBLEM TO BE SOLVED: To provide a liquid crystal composition simultaneously reduced in both the temperature dependency and frequency dependency of its threshold voltage at a service temperature, and to provide a liquid crystal element using the composition. SOLUTION: This liquid crystal composition comprised a compound of general formula I as a 1st component and, as a 2nd component, a compound of general formula II and/or a compound of general formula III, and has a nematic phase- isotropic liquid phase transition temperature of 75-130 deg.C, smectic phase- or solid phase-nematic phase transition temperature of -60 to -20 deg.C and birefringence (Δn) of 0.07-0.30 [in general formulas I, II and III, R1 to R3 are each a 1-16C (substituted) alkyl, 2-16C alkenyl or the like].
