Display Panel and Display Device Including the Same

A display device comprising:

• a display panel including a display part displaying an image and a non-display part disposed outside the display part and not displaying an image;
• a driving circuit unit supplying a common voltage to at least one first electrode and at least one second electrode during a display period, and supplying a touch signal to the at least one first electrode during a touch sensing period and refraining from supplying the touch signal to the at least one second electrode during the touch sensing period;
• and
• a controller driving the driving circuit unit,
• wherein the display panel comprises:
• a plurality of first electrodes provided in the display part of the display panel, the plurality of first electrodes used as a common electrode for displaying the image and the plurality of first electrodes used as a touch electrode for sensing touch;
• a plurality of second electrodes provided in the display part of the display panel, the plurality of second electrodes used as the common electrode for displaying the image and the plurality of second electrodes used as the touch electrode for sensing touch;
• a plurality of first electrode lines extending to the non-display part of the display panel that is disposed outside of the display part, each of the plurality of first electrode lines connected to a corresponding one of the plurality of first electrodes in a one-to-one correspondence relationship;
• and
• a plurality of second electrode lines extending to the non-display part, each of the plurality of second electrode lines connected to a corresponding at least two of the plurality of second electrodes,
• wherein at least one of the plurality of first electrode lines extends along a first direction and overlaps with at least one of the plurality of second electrode lines which extends along a second direction,
• wherein the at least one of the plurality of first electrode lines overlaps with at least one of the plurality of second electrodes, and the at least one of the plurality of first electrode lines overlaps with at least two of the plurality of the first electrodes,
• wherein the at least one of the plurality of second electrode lines overlaps with at least two of the plurality of second electrodes, and the at least one of the plurality of second electrode lines overlaps with at least two of the plurality of the first electrodes.
