Abstract: A display device includes a display panel including a plurality of pixels and a plurality of data lines connected to the pixels, and a data driver which provide a plurality of data voltages to the data lines. The data driver includes a plurality of channels, where each of the channels outputs an nth data voltage in an nth horizontal period, and outputs an (n+1)th data voltage in an (n+1)th horizontal period, where n is a natural number, a common line, a plurality of data switches, which selectively connect the channels to the data lines, respectively, a plurality of common switches, each of which selectively connects a corresponding one of the channels to the common line, and a voltage sensor which senses a common voltage of the common line.
