A liquid crystal display apparatus using a ferroelectric liquid crystal with negative dielectric anisotropy in which a blanking pulse having a width that is at least twice of a selecting period and a polarity opposite to a strobe pulse to be applied to a scanning electrode in the selecting period is applied to the scanning electrode before the selecting period during one frame period. Another liquid crystal display apparatus using a ferroelectric liquid crystal with negative dielectric anisotropy in which a strobe pulse is applied to a scanning electrode in a trailing part of the selecting period and a predetermined period that follows the selecting period. A blanking pulse of opposite polarity to the strobe pulse is applied to the scanning electrode before the selecting period in one frame period. A non-selecting period which is at least three times longer than the selecting period is provided between the blanking pulse and the selecting period.
