Abstract: Disclosed are an organic light emitting display device and a method of manufacturing the same. In the organic light emitting display, an anode connected to a thin film transistor and a bank disposed along the edge of the anode are simultaneously formed through one mask process, and a partition is formed to cover the side surface of the anode, thereby preventing damage to a pad cover electrode by an etching solution or etching gas of the anode without any separate pad protective film.

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.

Abstract: A display apparatus including two lines is provided. The two lines may extend in a first direction. A light-emitting device may be disposed between the two lines. Each line may be bent or extended in the direction of the device substrate which supports the light-emitting device. Thus, in the display apparatus, mixing of light emitted to the outside through the device substrate may be prevented. Therefore, in the display apparatus, the quality of realized image may be improved.
