PURPOSE:To obtain a liquid crystal composition which is particularly excellent in low temp. properties, by incorporating at least one member selected from among specific 11 compounds. CONSTITUTION:A liquid crystal composition containing at least one member selected from the compounds (1)-(8) of the formula I and the compound (9)-(11) of the formula II. In the formula, R1 is a 1-5C straight-chain alkyl; R1' a 1-5C straight-chain alkyl; R2 a 1-5C straight-chain alkyl; R2' a 2-8C straight-chain alkyl; R3 a 3-8C straight-chain alkyl; R3' a 3-8C straight-chain alkyl; R4 a 3-8C straight-chain alkyl; R4' a 3-8C straight-chain alkyl; R5 a 1-8C straight-chain alkyl; R6 a 2-10C straight-chain alkyl; R7 a 2-10C straight-chain alkyl; n8 an integer of 1-10; R9 a 2-10C straight-chain alkyl; R9' a 2-10C straight-chain alkyl; R10 a 2-10C straight-chain alkyl; R10' a 2-10C straight- chain alkyl; R11 a 2-10C straight-chain alkyl; and R11' a 2-10C straight-chain alkyl.
