A decahydronaphthalene derivative represented by general formula (I), a liquid-crystal composition containing the derivative; and a liquid-crystal element containing the composition. The decahydronaphthalene derivative, which is a novel compound, can be extremely easily produced even on an industrial scale as shown in Examples. When added to a base liquid crystal in a small amount, the derivative not only widens the nematic-phase temperature range but can improve various properties of the liquid-crystal material. The derivative has excellent compatibility with base liquid crystals currently in general use as nematic liquid crystals. Therefore, it is suitable for use in various liquid-crystal display elements required to operate in a wide temperature range and is extremely useful as a material for liquid crystals. |
