ABSTRACT:
The present invention was realized in order to provide a liquid crystal composition which is negative in dielectric constant anisotropy and having a large absolute value and a display element, and also to provide a compound which is negative in dielectric constant anisotropy and having a large absolute value.The present invention was realized in order to provide a trifluoronaphthalene derivative expressed by the general formula (I)a liquid crystal composition containing the above compound and a display element in which the liquid crystal composition is used. The liquid crystal composition of the present invention has features in which the dielectric constant anisotropy is great in absolute value, and a liquid crystal display element in which the liquid crystal composition is used as a constituting member is useful as a liquid crystal display element based on vertical alignment mode, IPS or others.
