The drive electrodes are also used as common electrodes for display, which are provided in the display panel.

In the driving operation of the electrodes for the touch sensor, a code division multiplexing (CDM) drive is performed in units of successive common electrodes, and a drive signal which synchronizes with the CDM drive is input to all common electrodes other than successive common electrodes subjected to the CDM drive.

In a frame 1, a sum total of luminance of a sub-pixel (SRX) and a sub-pixel (SRx) is caused to correspond to pixel data (DR1) while setting luminance of a sub-pixel (SRX) which is provided in a pixel (PRX) of a picture element (EX) to be higher than luminance of the sub-pixel (SRx) which is close to the sub-pixel (SRX) in the vertical direction in the pixel (PRX), and in a frame 2, a sum total of luminance of the sub-pixel (SRX) and the sub-pixel (SRx) is caused to correspond to pixel data (dR2) while setting luminance of the sub-pixel (SRx) to be higher than luminance of the sub-pixel (SRX).

The second sub GOA unit is configured to output a second scan driving signal. The first sub GOA unit and the second sub GOA unit share at least a portion of signal wirings, so that a width of the GOA device is narrowed while a circuit layout of the display panel is simplified.

A gate driving circuit and a display panel are provided. The gate driving circuit reduces the number of transistors through the inverter in the pull-down maintaining circuit such that the number of the signal output ends connected to the inverter is reduced. In this way, the number of the other transistors in the pull-down maintaining circuit is also reduced. Therefore, the number of the transistors and the number of the signal output ends of the pull-down maintaining circuit are both reduced. This means that the number of the transistors and the number of the signal output ends of the gate driving circuit are both reduced.
