A gate insulation layer is formed on the active layer, and a gate electrode is formed on the gate insulation layer over the active layer. A source and a drain electrodes are formed over the active layer, and connected to the source and drain regions, respectively. In the TFT region, an interlayer insulation layer is formed between the gate electrode and the source/drain electrodes. In the capacitor region, an interlayer insulation layer is formed between a capacitor lower electrode and a capacitor upper electrode to form a capacitor. The interlayer insulation layers of the TFT region and the capacitor region have different layer structures and have different dielectric constants. Therefore, the capacitor region can have higher capacitance while the TFT region can have lower capacitance to reduce parasitic capacitance.

Abstract: An organic light emitting display device and a method of fabricating the same are provided. A trench is formed in a planarization layer, and then a first electrode is formed to have opposite ends in the trench, thereby reducing a height difference between the planarization layer and the first electrode. That is, the thickness of a pixel defining layer formed on the first electrode may be reduced by reducing or minimizing protrusion of the first electrode with respect to the planarization layer. Thus, transfer efficiency can be increased when an organic layer is formed by a laser induced thermal imaging method, and reliability of a device can be improved by reducing or preventing thermal damage of the organic layer and open defects.

Abstract: A novel design for an electrode for a thin film transistor. The novel design allows for formation of a normal conductive channel between a source electrode and a drain electrode even after a heat treatment process, and a flat panel display including the thin film transistor. The thin film transistor includes a source electrode, a drain electrode, a gate electrode, and a semiconductor layer, wherein at least one of the source electrode, the drain electrode, and the gate electrode includes an aluminum alloy layer, and titanium layers are formed on both surfaces of the aluminum alloy layer. The electrodes are preferably absent any pure aluminum as pure aluminum can diffuse into the semiconductor layer causing a defect region and preventing a conductive channel from forming in the thin film transistor.
