PURPOSE:A liquid crystal composition, obtained by blending a specific Nn liquid crystal with Np liquid crystal and further specific compound, having a wide nematic liquid crystal temperature range, improved steepness, low optical threshold voltage and excellent dynamic driving characteristic. CONSTITUTION:A liquid crystal composition obtained by blending (A) preferably 8-90wt% compound expressed by formula I with (B) preferably 2-80wt% compound expressed by formula II, (C) preferably 3-42.5wt% compound expressed by formula III and (D) preferably 8-22.5wt% compound expressed by formula IV. In the above-mentioned formulas I-IV, R1, R2, R5, R6 and R7 are 1-10C straight-chain alkyl; R3 and R4 are 1-12C straight-chain alkyl.
