Abstract: An object of the present invention is to provide a flat display device which achieves an excellent and stable display even when the periodicity of voltage polarity is switched at the beginning of a frame at the time of driving a signal line while providing a periodicity of every M scanning lines to the voltage polarity of signal lines in each frame. A control circuit 22 controls so as to provide a voltage polarity of the final line in the periodicity of every four scanning lines to a signal line prior to driving a signal line corresponding to the first scanning line Y(1) at the beginning of a frame.

Abstract: A display method can be flexibly applied to suppress the power consumption and a device and display method which can reduce the power consumption while the image quality is prevented from being deteriorated are provided. A display device which can be operated in a progressive mode and interlace mode includes a display portion having a plurality of pixels arranged thereon and a gradation correction table which stores data used to correct a difference between a gradation level when the display portion is driven in the progressive mode and a gradation level when it is driven in the interlace mode. Then, when video data supplied to the display portion is set in the interlace mode, a timing controller corrects the video data by use of data in the gradation correction table.
