ABSTRACT:
A liquid crystal device is constituted by an electrode matrix including scanning electrodes and data electrodes intersecting the scanning electrodes, and a liquid crystal disposed to form a pixel at each intersection of the data electrodes and the scanning electrodes. The liquid crystal device is driven by sequentially applying a scanning selection signal to the scanning electrodes, and in synchronism with the scanning selection signal, applying data signals to the data electrodes, each data signal comprising a selection pulse of a first polarity having a pulse width .DELTA.T for determining a display state of a pixel and pulses of a second polarity disposed before and after the selection pulse, wherein the data signals are applied successively with a pause period shorter than .DELTA.T, preferably about .DELTA.T/2, between succeeding two data signals.
