PURPOSE:A liquid crystal composition, obtained by blending a specific Nn liquid crystal with Np liquid crystal and further specific compound and having a wide nematic liquid crystal temperature range, improved steepness, low optical threshold voltage and excellent dynamic driving characteristic. CONSTITUTION:A composition obtained by blending (A) preferably 8-90wt% compound expressed by formula I with (B) preferably 2-80wt% compound expressed by formula (C) preferably 3-42.5wt% compound expressed by formula III, (D) preferably <=10wt% compound expressed by formula IV and (E) preferably 8-22.5wt% compound expressed by formula V. In the above-mentioned formulas I-V, R1, R2, R5, R6, R7 and R8 are 1-10C straight-chain alkyl; R3 and R4 are 1-12C straight-chain alkyl.
