Patent ID: 8624249

Claim:
An organic light emitting display device, comprising: a substrate having a light emitting area and a non-light emitting area that is disposed outside the light emitting area to surround the light emitting area; a thin film transistor formed in the light emitting area of the substrate and comprising an active layer, a gate electrode comprising a gate lower electrode and a gate upper electrode, a source electrode, and a drain electrode; an organic light emitting device electrically connected to the thin film transistor and formed in the light emitting area of the substrate, the organic light emitting device comprising a pixel electrode formed of the same material as at least a part of the gate electrode in the same layer, an intermediate layer comprising a light emitting layer, and an opposed electrode arranged to face the pixel electrode are sequentially deposited; and a first pad electrode formed of the same material as the gate upper electrode in the same layer, and a second pad electrode electrically connected to the first pad electrode and formed of the same material as the source electrode and the drain electrode in the same layer and comprising an ion doped layer in which predetermined ions are doped in a surface opposite to a surface facing the substrate, the second pad electrode being formed in the non-light emitting area.
