A display device includes a sensing line and a data driver. The sensing line is in a display panel. The data driver includes a plurality of integrated circuits. Each of the integrated circuits includes an interface, which includes a mobile industry processor interface (MIPI) and a crack detector. The crack detector detects cracks of the panel based on the sensing line and transmits and receives information corresponding to the crack to and from adjacent ones of the integrated circuits using a transmission terminal and a reception terminal in the MIPI.
