Abstract: Disclosed are a display device and a method of manufacturing the same. In the disclosed display device, a pad cover electrode disposed on a pad area comes into contact with an upper surface and a side surface of a pad electrode since a planarization layer is disposed on an active area excluding the pad area, which may prevent contact failure between the pad cover electrode and a conductive ball. In addition, in the display device, a first electrode, which is connected to a thin film transistor via a pixel connection electrode, is formed via the same mask process as the planarization layer so that it has a line width similar to that of the planarization layer and overlaps the planarization layer, which may simplify a structure and a manufacturing process.
