PROBLEM TO BE SOLVED: To provide a liquid crystal composition having a moderate threshold voltage, high reliability and high anisotropic valueΔn of refractive index and a liquid crystal display device obtained by using the composition. SOLUTION: This liquid crystal composition is provided by including the first component composed of a compound represented by general formula (1) and the second component composed of at least one kind selected from the group composed of compounds represented by general formulae (2-1) and (2-2) (wherein, R<1> denotes a 1-10C alkyl; R<2> and R<3> denote each a 1-10C alkyl, a 1-10C alkoxy, a 2-10C alkoxymethyl or a 2-10C alkenyl, independently; Z1 and Z2 denote each -C2 H4 - or single bond, independently; X1 and X2 denote each F, Cl, CF3 , OCF3 , OCF2 H, a 1-10C alkyl, a 1-10C alkoxy, a 2-10C alkoxymethyl or a 2-10C alkenyl, independently; and Y1 , Y2 , Y3 , Y4 , Y5 , Y6 , Y7 , Y8 , Y9 and Y10 denote each H or F, independently). The liquid crystal display device is formed by using the composition.
