Claim Text:
1. A display device that performs display with a dot inversion driving method, comprising: a screen having a plurality of scanning signal lines and a plurality of data signal lines arranged in a matrix and pixels provided for respective intersections thereof; a signal line driver circuit that drives each of the data signal lines; and a driving power control unit that controls a driving power of the signal line driver circuit, wherein display is conducted by performing a scan to select each of the scanning signal lines and supplying data signals to the pixels on a selected scanning signal line from the data signal lines, and wherein, during a prescribed period of time between one driving period in which all of the scanning signal lines are scanned and a next driving period, an idle period is provided during which potentials of the plurality of data signal lines are kept constant, and during the idle period, the driving power control unit lowers a driving power of the signal line driver circuit, wherein the signal line driver circuit outputs the data signals to the respective data signal lines during the driving period, and during the idle period, the signal line driver circuit outputs to the respective data signal lines the data signal that was outputted to the respective data signal lines at a scanning signal line that was selected in the end of the driving period, such that the plurality of data signal lines have respective constant potentials.
