Abstract
In an organic light-emitting display apparatus and a method of manufacturing the same, a pad region of the organic light-emitting display apparatus comprises a protrusion layer including a plurality of protrusion portions formed on a substrate so as to protrude, a pad lower electrode and a pad upper electrode, the pad lower electrode including a protrusion portion formed along a protrusion outline of the protrusion layer and a flat portion formed along the substrate, and the pad upper electrode being formed on the flat portion of the pad lower electrode. A source/drain electrode layer is formed on the pad upper electrode, an organic layer is formed on the source/drain electrode layer, and a counter electrode layer is formed on the protrusion portion of the pad lower electrode and the organic layer. The counter electrode layer follows the protrusion outline of the protrusion layer on the protrusion portion. According to such a structure, cost is reduced due to a reduction in the number of masks, the manufacturing process is simplified, and a lifting phenomenon of the organic layer in the pad region is solved.
