摘要： A novel compound represented by general formula (I) and a nematic liquid crystal composition containing the same. A compound represented by general formula (I) can be produced with great ease as is shown in an example and has excellent compatibility with a mother liquid crystal of general use being currently used as a nematic liquid crystal, and further shows reduced precipitation at a low temperature. Moreover, the addition of only a small amount of the above compound to the mother liquid crystal results in expanding effectively the temperature range for liquid crystallinity, without detriment to various properties as a liquid crystal material. Accordingly, the above compound is suitable for use in various liquid crystal display elements which are required to have a wide range of working temperature and is greatly useful as a liquid crystal material.

摘要： A novel compound represented by the general formula (I), and a nematic liquid crystal composition incorporating the same.
A compound represented by the general formula (I) can be produced industrially extremely easily, as shown in the examples, displays superior compatibility with current general purpose host liquid crystals as a nematic phase, and also shows little crystal precipitation at low temperatures. Moreover, by addition of a small amount of such a compound to a host liquid crystal, the liquid crystal temperature range at low temperatures can be effectively widened without any significant worsening of the various characteristics of the liquid crystal material. Consequently, a compound of the present invention is an extremely useful liquid crystal material which is suitable for various liquid crystal display elements which require a broad operating temperature range.
