The present invention provides a nematic liquid crystal composition using a 4,6-difluoroindane-based compound that has a low lower limit temperature (T<SUB>->N</SUB>) of the liquid crystal phase, high upper limit temperature (T<SUB>N-I</SUB>) 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 Deltan 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° C. or higher, the liquid crystal phase lower limit temperature is -20° C. or lower, and the difference between the liquid crystal phase upper limit temperature and liquid crystal phase lower limit temperature is 90° C. or more.
