The first power source may be configured to apply the first voltage level and the second power source may be configured to apply the second voltage level during the period in which the gate of the first transistor is initialized, and the first power source may be configured to apply the second voltage level and the second power source may be configured to apply the third voltage level during a period in which the organic light emitting diode emits light.
For the period in which the gate of the first transistor is initialized, when the on-level scan signals are simultaneously applied to the plurality of scan lines, the light emission control driver may simultaneously apply the off-level light emission control signals to the plurality of light emission control signal lines, and when the off-level scan signals are simultaneously applied to the plurality of scan lines, the light emission control driver may be configured to simultaneously apply the on-level light emission control signals to the plurality of light emission control signal lines.
