A display device and a method of repairing the same are disclosed. In one aspect, the display device includes an OLED, a repair line electrically connected to a first dummy pixel and a second dummy pixel, and a repair modulation circuit electrically connected to the first and second dummy pixels. The first dummy pixel includes a first dummy pixel driving circuit configured to output a driving current corresponding to a data voltage of a selected pixel of the OLED to the repair line, when the selected pixel becomes defective, based on a first light emission control signal. The repair modulation circuit includes a capacitor configured to be initialized before the driving current is output from the first dummy pixel driving circuit. The capacitor of the repair modulation circuit is configured to be charged with the driving current when the driving current is output from the first dummy pixel driving circuit.
