A method for driving a surface-stabilized ferroelectric liquid crystal display element uses a selection voltage, a half-selection voltage, and a non-selection voltage. A relative ratio between the selection voltage, half-selection voltage, and non-selection voltage of a drive signal is changed, or absolute levels of the selection voltage, half-selection voltage, and non-selection voltage are changed. Consequently, a plurality of gradations of the surface-stabilized ferroelectric liquid crystal display element can be obtained.
