1. A display device, comprising:
a display panel in which a plurality of pixels is disposed;
a timing controller configured to output a sensing pulse and a video data signal; and
a data driver configured to apply the sensing pulse and outputs a data voltage to the plurality of pixels according to the video data signal, and including a plurality of source integrated circuits, each of the plurality of source integrated circuits receiving a plurality of delay pulses from the timing controller,
wherein the timing controller compares timings of the plurality of delay pulses to compensate for the video data signal,
wherein the data driver further includes a source printed circuit board connected to the plurality of source integrated circuits and a sensing line formed in the source printed circuit board and the plurality of source integrated circuits, and
wherein the sensing pulse is transmitted through the sensing line.
