Abstract:
1. An organic light-emitting display apparatus, comprising: a thin film transistor including an active layer, a gate electrode, a source electrode, a drain electrode, a first insulating layer between the active layer and the gate electrode, and a second insulating layer between the gate electrode and the source electrode and the drain electrode; a pad electrode including a first pad layer on a same layer as the source electrode and the drain electrode and a second pad layer disposed on the first pad layer; a third insulating layer covering the source electrode and the drain electrode and an end portion of the pad electrode, the third insulating layer including an organic insulating material; a pixel electrode including a semi-transmissive metal layer, the pixel electrode being in an opening in the third insulating layer; a cathode contact unit including a first contact layer on the second insulating layer, a second contact layer on the first contact layer, and a third contact layer on the second contact layer; a fourth insulating layer covering the end portion of the pad electrode; an organic emission layer on the pixel electrode; and an opposing electrode on the organic emission layer.
