Patent ID: 8643019

Claim:
An organic light emitting display device, comprising: a thin film transistor comprising an active layer, a gate electrode including a gate lower electrode and a gate upper electrode, a source electrode, and a drain electrode; an organic light emitting unit electrically connected to the thin film transistor, the organic light emitting unit comprising a pixel electrode formed of a same material and in a same layer as the gate lower electrode, an opposed electrode, and an intermediate layer comprised of a light emitting layer and interposed between the pixel electrode and the opposed electrode; a first pad electrode formed of the same material and in the same layer as the gate lower electrode; a second pad electrode formed on at least a part of the first pad electrode and formed of a same material and in a same layer as the gate upper electrode; and a third pad electrode contacting at least a part of the second pad electrode and formed of a same material and in a same layer as the source electrode.
