Document Type and Number:
Japanese Patent JP5859802
Kind Code:
B2
Abstract:
An organic light emitting display device comprises a thin film transistor including an active layer, a gate electrode including a gate lower electrode and a gate upper electrode, a source electrode, a drain electrode, and an organic light emitting device electrically connected to the thin film transistor. A pixel electrode formed of the same material and in the same layer as the gate lower electrode, an intermediate layer including a light emitting layer, and an opposed electrode are sequentially deposited. A first pad electrode is formed of the same material and in the same layer as the gate lower electrode, a second pad electrode is formed on at least a part of the first pad electrode and is formed of the same material and in the same layer as the gate upper electrode, and a third pad electrode contacts at least a part of the second pad electrode and is formed of the same material and in the same layer as the source electrode.
