Abstract: An organic light emitting display device includes a substrate. A buffer layer is disposed on the substrate. The buffer layer includes a first opening exposing an upper surface of the substrate in a bending region. Pixel structures are positioned in a pixel region on the buffer layer. A fan-out wiring is positioned in the peripheral region and the pad region on the insulation layer structure such that the upper surface of the substrate and the first portion of the buffer layer are exposed. A passivation layer is disposed on the fan-out wiring, side walls of the insulation layer structure adjacent to the bending region, and the first portion of the buffer layer. The passivation layer includes a third opening exposing the upper surface of the substrate in the bending region. A connection electrode is positioned in the bending region on the substrate.

Abstract: An organic light emitting display device includes an (i−1)th pixel, an i-th pixel, and an (i+1)th pixel, each including an organic light emitting diode and a driving transistor to control a driving current flowing through the organic light emitting diode. A first node of the i-th pixel, to which a control electrode of the driving transistor of the i-th pixel is connected, is initialized to an initialization voltage in synchronization with an (i−1)th scan signal applied to the i-th pixel, and an anode of the organic light emitting diode of the i-th pixel is initialized to the initialization voltage in synchronization with an i-th scan signal applied to the (i+1)th pixel.
