    Abstract: There is provided a liquid crystal composition containing the compound represented by the general formula (1) and a liquid crystal display device that uses the liquid crystal composition. The compound represented by the general formula (1) has high Δ∈, high Tni, and good miscibility with other liquid crystal compounds. Therefore, a liquid crystal composition that has high Δ∈ and exhibits a liquid crystal phase in a wide temperature range can be obtained by using the compound represented by the general formula (1) as a component of the liquid crystal composition. Thus, the compound is very useful as a constituent component of the liquid crystal composition for liquid crystal display devices.
