Abstract
A display device includes a scan driver which supplies a gate-on voltage or a gate-off voltage to scan lines, and a power supply unit which supplies the gate-off voltage to the scan driver, and includes a temperature sensor which generates a sensing voltage of which voltage value is changed corresponding to a temperature of a panel or an ambient temperature, a first voltage limiter which limits a minimum voltage value of the sensing voltage, and a second voltage limiter which limits a maximum voltage value of the sensing voltage.
