A precharge circuit configured to precharge source bus lines is provided in a display device employing an SSD method. In the case where an n-channel TFT is employed, the precharge circuit applies a precharge voltage to the source bus line connected to the pixel formation portions to be subjected to data writing of a positive polarity, before a video signal is applied to the source bus line. In each horizontal scanning period, an SSD circuit switches the source bus line of a connection. destination of a data output line so that the video signal is applied to the source bus line connected to the pixel formation portions to be subjected to the data writing of a negative polarity relatively prior to the source bus line connected to the pixel formation portions to be subjected to the data writing of the positive polarity.
A display device comprising a plurality of video signal lines, a plurality of scanning signal lines intersecting with the plurality of video signal lines, a plurality of pixel formation portions arranged corresponding to respective intersections between the plurality of video signal lines and the plurality of scanning signal lines, and a scanning signal line drive circuit configured to drive the plurality of scanning signal lines, the display device comprising:
The display device according to clam 2, wherein
A method for driving a display device including a plurality of video signal lines, a plurality of scanning signal lines intersecting with the plurality of video signal lines, a plurality of pixel formation portions arranged corresponding to respective intersections between the plurality of video signal lines and the plurality of scanning signal lines, a scanning signal line drive circuit configured to drive the plurality of scanning signal lines, a video signal line drive circuit configured to output a video signal to a data output line in a time division. manner in each horizontal scanning period, and a connection switching circuit including a connection control transistor configured to control an electrical connection state between each of the video signal lines and the data output line corresponding thereto, the data output line corresponding to each video signal line group obtained by grouping the plurality of video signal lines with K video signal lines set as one group, where K is an integer of two or more, the connection switching circuit configured to switch a connection destination of the data output line corresponding to each of the video signal line groups among the K video signal lines configuring each of the video signal line groups, the method comprising:
