Embodiments of the present invention relate to a display device, which can properly take action by detecting a malfunction of a driver due to an abnormal driving voltage, and a data driver. The display device comprises: a display panel; a power supply unit for supplying a driving voltage to a driver; a plurality of drivers receiving the driving voltage supplied by the power supply unit, and driving the display panel; a sensing unit for sensing the driving voltage, and converting the sensed driving voltage into power sensing data with a digital form; and a timing controller for providing a power control signal, which compensates the driving voltage, to the power supply unit based on the sensed driving voltage. |
