The present invention provides a novel liquid crystal compound and a method for producing the same, and a liquid crystal composition for STN and TFT capable of having a wide N-phase temperature range, a small refractive index anisotropy, a low voltage drive, a high-speed response, and the like. The general formula (I) (R: H atom, C 1-10 alkyl group, n: 1-10, X a , X b , X c : H atom, F atom, Z: H atom, halogen atom, alkyl group, alkoxyl group, An alkenyl-substituted decahydronaphthalene derivative represented by an alkenyl group, an alkenyloxy group, and the like, a liquid crystal composition containing the same, and a liquid crystal element including the same as a constituent element.
