ABSTRACT:
A method for driving an active matrix substrate including a plurality of scanning electrode lines, a plurality of data electrode lines, and a plurality of pixel electrodes respectively connected to the scanning electrode lines and the data electrode lines via a ferroelectric material. According to the method, a data writing pulse having a first polarity is applied to a scanning electrode line selected from the plurality of scanning electrode lines in a selection period. A data writing prohibiting pulse having a level of 0 is applied to the selected scanning electrode line in a first period included in a non-selection period following the selection period. In the first period, a data writing pulse having the first polarity is applied to a scanning electrode line different from the selected scanning electrode line. A data writing prohibiting pulse having the first polarity is applied to the selected scanning electrode line in a second period included in the non-selection period. In the second period, a data writing pulse having a second polarity is applied to a scanning electrode line different from the selected scanning electrode line. A data pulse having the second polarity or a level of 0 is applied to the respective plurality of data electrode lines in the first period. A data pulse having the first polarity or a level of 0 is applied to the respective plurality of data electrode lines in the second period.
