  • Patent number: 8415675
    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.
