Abstract:
1. An organic light-emitting display apparatus, comprising: at least one transistor, each comprising a semiconductor layer, a gate electrode and source and drain electrodes; a first capacitor including a first electrode formed coplanar with the semiconductor layer, a second electrode formed on a same plane as the gate electrode, and a third electrode formed on a same plane as the source and drain electrodes, the first electrode of the first capacitor comprising a semiconductor which is not doped with ion impurities; a second capacitor including a first electrode formed coplanar with the semiconductor layer and a second electrode formed on the same plane as the gate electrode, a portion of the first electrode of the second capacitor, which overlaps an insulating layer interposed between the first and second electrodes of the second capacitor and which overlaps the second electrode of the second capacitor, comprising ion impurities, the second electrode of the second capacitor including a second layer and a first layer disposed between the insulating layer and the second layer of the second electrode of the second capacitor, a center portion of the second layer of the second electrode of the second capacitor including an opening exposing a center portion of the first layer of the second electrode of the second capacitor; a pixel electrode formed on the same plane as the gate electrode and electrically connected to said at least one transistor; a light-emitting layer disposed on the pixel electrode; and an opposite electrode disposed on the light-emitting layer and facing the pixel electrode.
