Organic light-emitting display apparatus

An organic light-emitting display apparatus comprising:

• a substrate;
• a thin-film transistor (TFT) on the substrate and comprising an active layer, a gate electrode, a source electrode, and a drain electrode;
• a first interlayer insulating layer between the gate electrode and the source and drain electrodes and comprising an inorganic material;
• a second interlayer insulating layer between the first interlayer insulating layer and the source and drain electrodes and comprising an organic material;
• a first organic layer covering the source electrode and the drain electrode;
• a second organic layer on the first organic layer;
• a capacitor comprising a first electrode comprising a same material as the gate electrode, and a second electrode comprising a same material as the source electrode and the drain electrode;
• a pixel electrode in an opening in an area that does not overlap with the TFT and the capacitor, and contacting one of the source electrode and the drain electrode;
• an emission layer on the pixel electrode;
• and
• an opposite electrode on the emission layer.
