A display device includes a switching circuit; a sub-pixel having a driving transistor and an organic light emitting diode (OLED) with an anode connected to the driving transistor; a driving voltage supply line to supply a driving voltage to the OLED through the driving transistor; a base voltage supply line connected to a cathode of the OLED through the switching circuit; a ground line to supply a ground voltage to the switching circuit; a first capacitor between the driving voltage supply line and the ground line; and a second capacitor between the base voltage supply line and the ground line. The switching circuit selectively supplies one of a first level voltage and a second level voltage as the base voltage, and the second level voltage is higher than the first level voltage at the ground voltage.
