Abstract:
1. An organic light emitting device comprising: a transistor on a substrate and including gate, source, and drain electrodes, the source and drain electrodes each including first and second layers; a first electrode connected to one of the source or drain electrodes; an organic emitting layer on the first electrode; and a second electrode on the organic emitting layer, wherein the first electrode includes a metallic layer and a conductive layer, wherein a tapered angle of the first layer lies in a range substantially between 70° and 90°, and a tapered angle of the second layer lies in a range substantially between 40° and 50°, wherein a thickness of the first layer is substantially 400 Å to 450 Å, and a thickness of the second layer is substantially 70 Å to 100 Å, wherein a tapered angle of the metallic layer lies in a range substantially between 35° and 70°, and a tapered angle of the conductive layer lies in a range substantially between 70° and 90°.
