A liquid crystal display method is provided in which various types of display patterns can be displayed with a predetermined driving voltage margin being maintained and power consumption does not increase. Accordingly, a driving method for a liquid crystal display device is provided using liquid crystal having two metastable states. A scanning signal has a reset period, a delay period, a selection period and a non-selection period in one frame period. The selection period is set to one horizontal scanning period 1H. The scanning signal is set to reset potentials reversed at an interval of a frame period in the reset period, set to selection potentials reversed at an interval of 1H/2 in the selection period, and set to non-selection potentials in the delay period and the non-selection period. The data potential of a data signal has potentials reversed at an interval of 1H/2. When the voltage difference between the scanning signal and the data signal is applied to the liquid crystal, a voltage having one polarity is not always applied to the liquid crystal for a period exceeding a 1H period in the delay period. Therefore, various display patterns can be displayed with a predetermined driving voltage margin being maintained. Since a voltage applied to the liquid crystal in the reset period is reversed in the positive and negative sides at an interval of a period longer than 1H, power consumption does not increase.
