The present invention provides a nematic liquid crystal composition using a 4, 6-difluoroindane-based compound that has a low lower limit temperature (T->N) of the liquid crystal phase, high upper limit temperature (TN-I) of the liquid crystal phase, and wide liquid crystal phase temperature range without impairing response speed, threshold voltage and other liquid crystal characteristics within a the range of the optimal DELTA n as a nematic liquid crystal, and a 4,6-difluoroindane-based compound that is used in said liquid crystal composition. <??>The nematic liquid crystal composition contains at least one type of compound having a 4, 6-difluoroindan-2, 5-diyl group, and the refractive index anisotropy is within the range of 0.08 to 0.15, the liquid crystal phase upper limit temperature is 70 DEG C or higher, the liquid crystal phase lower limit temperature is -20 DEG C or lower, and the difference between the liquid crystal phase upper limit temperature and liquid crystal phase lower limit temperature is 90 DEG C or more. |
