Claim:
1. A display device, comprising: a display panel; a data driver configured to supply a data signal to the display panel; and a scan driver formed in a non-display area of the display panel, including a shift register composed of a plurality of stages and a level shifter formed outside the display panel, and configured to supply a scan signal to the display panel using the shift register and the level shifter, wherein the scan driver comprises: a sensor circuit unit configured to sense internal and external environmental conditions and to generate a compensation circuit control signal on the basis of a sensed result; and a compensation circuit unit configured to generate a compensation signal for compensating outputs of the plurality of stages in response to the compensation circuit control signal, wherein the compensation circuit unit comprises a first transistor having a gate electrode and a first electrode connected to a first output terminal of the sensor circuit unit, and a second electrode connected to a compensation node of the compensation circuit unit.
