Patent ID: 8766265

Claim:
An organic light-emitting display device comprising: a thin film transistor (TFT) comprising: an active layer, a gate electrode, a source electrode, a drain electrode, a first insulating layer disposed between the active layer and the gate electrode, and a second insulating layer disposed between the source electrode and the drain electrode; a pixel electrode disposed on the first insulating layer and the second insulating layer, and connected to one of the source electrode and the drain electrode; a capacitor comprising: a first electrode disposed on a same layer as the active layer, a second electrode disposed on the same layer as the gate electrode, and a third electrode formed of the same material as a material of the pixel electrode, wherein the second insulating layer is not disposed between the second electrode and the third electrode; a third insulating layer disposed between the second insulating layer and the pixel electrode, and further disposed between the second electrode and the third electrode; a fourth insulating layer covering the source electrode, the drain electrode, and the third electrode, and exposing a portion of the pixel electrode; an organic light-emitting layer disposed on the pixel electrode; and a counter electrode disposed on the organic light-emitting layer.
