• a scan driver for driving a plurality of scan lines and a plurality of emission control lines,
• wherein the scan driver is configured to sequentially supply a plurality of scan signals to the scan lines and to sequentially supply a plurality of emission control signals to the emission control lines,
• wherein the scan driver is further configured to supply a plurality of inverted emission control signals generated by inverting the emission control signals to a plurality of inverted emission control lines extending in a direction parallel with the emission control lines;
• a data driver for driving a plurality of data lines;
• a display unit including pixels at crossing regions of the scan lines and the data lines;
• a plurality of first power source lines coupled to a first power source configured to supply a first voltage and coupled to the pixels in columns;
• a plurality of horizontal power source lines extending in a direction parallel with the scan lines and coupled to the pixels in rows;
• a second power source line coupled to the horizontal power source lines and coupled to a second power source configured to supply a second voltage equal to the first voltage;
• and
• a plurality of first switching elements, each of the first switching elements being coupled between a respective horizontal power source line of the horizontal power source lines and the second power source line;
• wherein each of the pixels comprises a driving transistor directly coupled to a corresponding one of the first power source lines and having a gate electrode electrically coupled to a storage capacitor,
• and wherein each of the pixels is configured to store a third voltage corresponding to the second voltage of the second power source and a data signal voltage supplied by the data driver and is configured to control an amount of current that flows from the first power source in accordance with the third voltage,
• wherein a first switching element of the plurality of switching elements in an ith row is configured to be turned on when a corresponding inverted emission control signal of the inverted emission control signals is supplied to an ith inverted emission control line of the inverted emission control lines and is configured to be turned off when the corresponding inverted emission control signal is not supplied to the ith inverted emission control line.
