PROBLEM TO BE SOLVED: To reduce power consumption in display devices, such as a simple matrix liquid crystal display device. SOLUTION: The driving method of the display device has N scanning lines (N is a 2 or more integer) Y1-Y120, M data lines (M is a 2 or more integer), a plurality of display elements (liquid crystal) of which the display state is controlled by voltage applied to the scanning line, and the voltage applied to the data line, drive circuits 50 and 6 of the scanning line, and the drive circuits 10-40 of the data lines. A display control signal is inputted in the drive circuit of the scanning line, the K scanning lines (for example, K=N/2) continuing among the N scanning lines by the display control signal are excepted from a target of selection, the scanning line of the (N-K=N/2) piece is displayed as the target of selection, and the driving of the scanning line of the (N-K) lines is performed. In this case, compared with the case when the driving of the N scanning lines is performed, voltage level at the time of the selection of the scanning line is lowered by a variable power source 510.
