摘要：
A liquid crystal composition used for a display element using TN (twisted nematic) mode or STN (super-twisted nematic) mode, having reduced threshold voltage and temperature dependency is provided,which composition is constituted by the following formulas (1) and (2): ##STR1## wherein R.sup.1 and R.sup.2 are an alkyl group of 1 to 10C; A.sup.1 and A.sup.2 each independently are 1,4-cyclohexylene or 1,4-penylene;n is 0 or 1; and X is H or F, andwhen 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.
