Abstract
Disclosed are an organic light-emitting display device and a method of manufacturing the same. In the organic light-emitting display device, a first protrusion is provided to protrude from a planarization layer, which has a pixel contact hole configured to expose a thin-film transistor disposed on a substrate, toward a cathode electrode of an organic light-emitting element, and a side surface angle of the first protrusion differs from a side surface angle of the planarization layer, which is exposed through the pixel contact hole. Thereby, the cathode electrode and an auxiliary connection electrode may be electrically connected to each other without a separate partition, which may simplify the structure and the manufacturing process of the organic light-emitting display device.
