Claim:
1. A display device, comprising: a first substrate; a plurality of pixel electrodes disposed on the first substrate; a common electrode comprising a plurality of common electrode plates disposed on the first substrate, wherein the common electrode plates cover the pixel electrodes and are arranged substantially in a matrix form; a plurality of common electrode line groups which applies a common voltage to the common electrode plates; and a plurality of touch signal lines to which the common voltage and a sensing input signal are applied, wherein laterally adjacent common electrode plates of the common electrode plates are connected to different common electrode line groups, each of the plurality of common electrode line groups includes a plurality of common electrode lines that are connected to one of the plurality of common electrode plates and commonly connected to a single touch signal line of the plurality of touch signal lines, and each of the plurality of common electrode line groups transmits the sensing input signal to one of the plurality of common electrode plates and a sensing output signal from the one of the plurality of common electrode plates.
