Abstract: A light emitting display device includes a substrate including a display area including a plurality of sub-pixels and a non-display area surrounding the display area, a plurality of first electrodes provided in the plurality of sub-pixels, a second electrode facing the plurality of first electrodes and extending over the entire display area and a part of the non-display area, an interlayer including a plurality of stacks provided between the plurality of first electrodes and the second electrode and a charge generation layer between the plurality of stacks, a first connection electrode provided in the non-display area and connected to the second electrode, and a second connection electrode disposed closer to the display area than the first connection electrode and connected to the charge generation layer, thus stabilizing the potential of a common layer having high mobility by using a connection electrode to prevent lateral leakage current caused by the common layer.
