  Disclosed is a novel liquid-crystalline compound which is a naphthalene derivative useful as an electro-optical liquid crystal display material, a liquid crystal composition containing such naphthalene derivatives and a liquid crystal display device comprising the same. The naphthalene derivative provided by the present invention exhibits an excellent liquid-crystallinity and miscibility with currently widely used liquid crystal compositions or compositions. The addition of the naphthalene derivative makes it possible to drastically lower the threshold voltage of the liquid crystal composition while maintaining its high response. The naphthalene derivative of the present invention is characterized by a large birefringence index. Further, most of the naphthalene derivative of the present invention has no strongly polar group in its molecule and thus can also be used for active matrix driving. Moreover, as shown in the foregoing examples, the naphthalene derivative of the present invention can be easily produced and is colorless and chemically stable. Accordingly, the liquid crystal composition comprising the naphthalene derivative of the present invention is extremely useful as a practical liquid crystal composition, particularly a liquid crystal composition which can operate within a wide temperature range and requires a high speed response and a low voltage driving.

  本发明公开了一种可用作电光液晶显示材料的新型液晶化合物（一种萘衍生物）、一种含有这种萘衍生物的液晶组合物以及一种包含这种萘衍生物的液晶显示装置。本发明所提供的萘衍生物具有极佳的液晶性，并可与目前广泛使用的液晶组合物或成分混溶。加入萘衍生物后，液晶组合物的阈值电压可大幅降低，同时保持高响应。本发明的萘衍生物具有双折射指数大的特点。此外，本发明的大多数萘衍生物分子中没有强极性基团，因此也可用于活性基质驱动。此外，如上述实例所示，本发明的萘衍生物易于生产，且无色、化学性质稳定。因此，包含本发明萘衍生物的液晶组合物作为实用液晶组合物，特别是作为可在宽温度范围内工作、需要高速响应和低电压驱动的液晶组合物，是非常有用的。
