Abstract: In a method of driving with a one-line-at-a-time scanning system a liquid crystal matrix display device in which the picture elements are defined by liquid crystal cell portions formed between the scanning and the signal electrodes arranged in the form of a matrix, the amplitude of the voltage applied to non-selected cells along a selected scanning electrode is made different from the amplitude of the voltage applied to non-selected cells along a selected signal electrode; the amplitude of the voltage (bias voltage) applied to non-selected cells along the selected signal electrode is made equal to the amplitude of the voltage applied to the remaining non-selected cells; and the bias voltage is determined depending on the number of the scanning electrodes, so that the operation margin is further improved.
