As a liquid crystal material for a low voltage driving TFT type liquid crystal display element, the voltage holding ratio is high, the Δε value is remarkably large, it is electrically and chemically stable, and the compatibility with existing liquid crystalline compounds is also good. Liquid crystal compound, a liquid crystal composition containing the same, and a liquid crystal display device formed using the same are provided. A specific dioxane derivative represented by the general formula (1). A liquid crystal composition comprising at least one of the derivatives. A liquid crystal display element constituted by using the liquid crystal composition. R represents an alkyl group, etc., and Q1 and Q2 represent H, F, and the like. A represents a group having a dioxane ring, and A0 and A1 represent a phenylene group or a cyclohexylene group. Za and Zb each represent a linking group exemplified by a single bond, and n1 and n2 each represents an integer of 0 or 1. [Selection figure] None |
