1. A display device, comprising:
a display panel comprising a plurality of pixels arranged in a matrix form, each of the plurality of pixels including N subpixels arranged in a first direction and having different colors, wherein N is 3 or 4, and a plurality of sensing lines disposed in a second direction between the plurality of pixels and configured to sense characteristic values for a plurality of subpixels electrically connected thereto; and
a data driving circuit configured to supply a data voltage to the display panel and sense the characteristic values for the plurality of pixels through the plurality of sensing lines,
wherein the N subpixels are disposed so that subpixels of a same color are symmetrical with respect to a corresponding sensing line among the plurality of sensing lines while the subpixels of the same color are connected to the corresponding sensing line together, and
wherein the data driving circuit is configured to initialize the sensing line to a reference voltage, and track the sensing line to sense a characteristic value charged to the sensing line after a predetermined time.
