1. A display device comprising: a display panel including a plurality of pixels, and a plurality of data lines connected to the pixels; and a data driver which provides a plurality of data voltages to the data lines, wherein the data driver includes: a plurality of channels, wherein each of the channels outputs an n.sup.th data voltage in an n.sup.th horizontal period, and outputs an (n+1).sup.th data voltage in an (n+1).sup.th horizontal period, wherein n is a natural number; a common line; a plurality of data switches which selectively connects the channels to the data lines, respectively; a plurality of common switches, wherein each of the common switches 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; wherein the data driver further includes a voltage comparator which compares the common voltage, the n.sup.th data voltage, and the (n+1).sup.th data voltage with each other; wherein a channel among the channels is connected to the common line by a common switch corresponding thereto among the common switches when the common voltage is between the n.sup.th data voltage of the channel and the (n+1).sup.th data voltage of the channel.
