Abstract: A display device includes a data driver for applying a data signal to a data line; a gate driver for applying a gate signal to a gate line; a level shifter for shifting a voltage level of a signal applied to the gate driver; and a signal controller for controlling the data driver, the level shifter, and the gate driver, wherein when a signal exchange between the data driver and the signal controller has an abnormality, the signal controller maintains a control signal applied to the level shifter in an off level.
