PROBLEM TO BE SOLVED: To provide a liquid crystal driving method permitting to drive a liquid crystal while applying a reset voltage of a relatively large absolute value generating Frederiks transition. SOLUTION: As a 7-level driving method, two kinds of potentials (foe example,±Vb) are set for applying an ON-selection voltage or an OFF-selection voltage to a liquid crystal as a data potential of a column electrode signal Yn; two kinds of potentials (for example,±Vr) are set respectively for applying a positive or a negative reset voltage to the liquid crystal for a reset period T1 as a data potential of a row electrode signal Xm; two kinds of potentials (for example,±2Vb) are set respectively for applying a positive or a negative selected voltage to the liquid crystal for a reset period T3 as a selected potential; and as a non-selected voltage, a middle potential (for example, 0V) between the two kinds of selected voltages is set for a delay period and a non-selected period. Thus, the liquid crystal can be driven by using the potentials at 7 levels.
