A liquid crystal composition used for a display element using TN (twisted nematic) mode or STN (super-twisted nematic) mode, having reduced the threshold voltage and its temperature dependency is provided,
which composition comprises in one embodiment compounds of the following formulas (1) and (2):
wherein R¹ and R² is an alkyl group of 1 to 10C; A¹ and A² each independently are 1,4-cyclohexylene or 1,4-penylene; n is 0 or 1; and X is H or F, and
when the liquid crystal composition of the present invention is used, it is possible to realize a liquid crystal display element superior in low voltage drive, low power consumption and contrast.
