摘要： A thin film transistor and a method of manufacturing the same are disclosed. More specifically, there is provided a thin film transistor having a thin film transistor and a method of manufacturing the same wherein an inorganic layer and an organic planarization layer are sequentially formed on the surface of a substrate on source/drain electrode of a thin film transistor having a semiconductor layer, a gate, source/drain areas and the source/drain electrodes, and a blanket etching process is performed to the organic planarization layer to planarize the inorganic layer. After forming a photoresist pattern on the inorganic layer, an etching process is performed to form a hole coupling a pixel electrode with one of the source/drain electrodes. According to the manufacturing method, the hole may be formed using one mask, thereby simplifying a manufacturing process, and improving an adhesion with the pixel electrode by the inorganic layer formed above. This thin film transistor may be appropriately applied to the active matrix organic electro luminescence display.

摘要： 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.
