Abstract:
1. An organic light-emitting display device, comprising: an organic light-emitting device; a thin film transistor (TFT) electrically connected to the organic light-emitting device; and a capacitor electrically connected to the organic light-emitting device, the capacitor including a first electrode layer and a second electrode layer opposite to each other, and a first insulating layer interposed as a single layer directly between the first electrode layer and the second electrode layer, the second electrode layer having a same thickness as source/drain electrodes of the TFT, wherein the TFT includes: a gate insulating layer only on a gate electrode and sidewalls thereof, the gate insulating layer being different from the first insulating layer, the gate electrode including a same material with a same thickness as the first electrode layer of the capacitor, the gate electrode and the first electrode layer being positioned directly on a same element and having leveled upper surfaces; and a second insulating layer directly between an active layer and the source/drain electrodes, the second insulating layer being a continuous layer with the first insulating layer of the capacitor, the active layer directly on horizontal and projected portions of the gate insulating layer not covering vertical sidewall portions of the gate insulating layer, the source/drain electrodes on the second insulating layer and connected to the active layer, the source/drain electrodes including a same material as the second electrode layer of the capacitor, wherein the organic light-emitting device and the TFT are in a non-overlapping relationship.
