A display device has a display array, a discharging line and a plurality of protection circuits. Each of the protection circuits has a first discharging circuit and a second discharging circuit. The first discharging circuit has a first switching element, a resistance element and a second switching element electrically connected in series between the discharging line and a scan line or a data line. The second discharging circuit has a third switching element, the resistance element and a fourth switching element electrically connected in series between the discharging line and the associated scan or data line. The second switching element is electrically connected to the third switching element, and both of them are switched by the resistance element.
