Abstract: A data driver and a display device using the same are disclosed. The display device includes a display panel having a display area displaying an image, signal lines including data lines, first power lines, and sensing lines connected to the display panel, and a data driver connected to the signal lines. The data driver includes first channel groups outputting a data signal, second channel groups outputting and sensing a sensing voltage, and third channel groups outputting a high potential voltage. The first channel groups and the third channel groups are defined as a first output unit, and the second channel groups are defined as a second output unit. The second channel groups are successively disposed every M channels, where M is an integer equal to or greater than 2.
