Abstract: An organic light-emitting display apparatus includes a substrate having a display area displaying an image and a periphery area. The periphery area is located next to the display area. A first organic insulating layer is disposed on the substrate. The first organic insulating layer includes a valley portion separating the first organic insulating layer from the periphery area. A plurality of organic light-emitting devices is disposed on the substrate. Each of the organic light-emitting devices includes a first electrode, an emission layer, and a second electrode, sequentially disposed over the first organic insulating layer. The second electrode covers the emission layer and the valley portion. A second organic insulating layer is disposed over the first organic insulating layer and includes a first opening exposing a center portion of the first electrode and a second opening overlapping the valley portion. A capping layer covers the second electrode.

Abstract: An organic light emitting display (OLED) device includes an organic light emitting diode having an anode and a cathode. The organic light emitting diode is configured to receive a reference voltage. A control transistor includes a first control electrode and a first semiconductor active layer. The control transistor is configured to receive a control signal. A driving transistor includes a second control electrode that is electrically connected to the control transistor, an input electrode that is configured to receive a power voltage, an output electrode that is electrically connected to the anode of the organic light emitting diode, and a second semiconductor active layer that includes a different material from that of the first semiconductor active layer. A shielding electrode is disposed on the second semiconductor active layer, overlapping the driving transistor, and configured to receive the power voltage.
