Abstract: An organic light emitting device having a repair line connected to an organic light emitting element of a bad pixel. A first capacitor stores a voltage corresponding to a data voltage of the bad pixel, and a driving transistor outputs a current corresponding to the voltage stored in the first capacitor to an output terminal. A first transistor is connected between the output terminal of the driving transistor and the repair line, and is turned on or turned off in response to a first signal. A second transistor is connected between the repair line and a node, and is configured to be turned on or turned off in response to a second signal. A third transistor is connected between a node and a first voltage line for supplying a first voltage, and is turned on or turned off in response to a third signal.
