Claim Text:
1. A display apparatus comprising: a display panel that includes a first substrate comprising an upper part on which a touch event that occurs, a second substrate disposed under the first substrate, and a liquid crystal layer disposed between the first substrate and the second substrate; and a touch sensor that calculates coordinate information of a position at which the touch event occurs, wherein the first substrate comprises: a base substrate; a plurality of common electrodes disposed under the base substrate, the plurality of common electrodes receiving a reference voltage during a display period and receiving touch sensing signals during a non-display period; a plurality of pixel electrodes overlapping with the plurality of common electrodes; a plurality of data lines; and a plurality of gate lines extending in a direction crossing the plurality of data lines; wherein the plurality of data lines comprises: first data line groups that intersect with the plurality of common electrodes, the first data line groups receiving first data voltages during the display period and being capacitively coupled to the plurality of common electrodes during the non-display period; and second data line groups that are alternately arranged with the first data line groups and receive second data voltages during the display period.
