A display device according to an example of the present disclosure includes a substrate in which an emission area and a non-emission area are divided and a plurality of sub-pixels are defined, an insulating layer disposed on the substrate, a first electrode disposed in each of the plurality of sub-pixels, a bank disposed on the insulating layer and exposing the first electrode through an opening thereof, an organic layer disposed on the first electrode, and a second electrode disposed on the organic layer. The bank includes exposed side surfaces by removing one area thereof between the plurality of sub-pixels, an undercut structure inwardly from lower ends of the exposed side surfaces. The bank further includes exposed side surfaces by removing an area thereof between the plurality of sub-pixels, and a trench structure by removing a portion of a thickness of the insulating layer.

Display device

An organic light emitting display device and a method of manufacturing the same are provided that may reduce the resistance of a second electrode and may prevent corrosion and metal migration of a pad electrode without adding a separate mask process, or while reducing the number of mask processes. In the organic light emitting display device, an auxiliary line is connected to a second electrode through an auxiliary electrode, which is provided in the same layer as a first electrode, and a pad cover electrode is configured to cover an upper surface and a side surface of a pad connection electrode so as to prevent the pad connection electrode connected to a pad from being exposed outward.

Organic light emitting display device and method of manufacturing the same

An organic light-emitting display device includes a substrate; a switching thin-film transistor on the substrate; a driving thin-film transistor connected to the switching thin-film transistor; and a light-emitting element connected to the driving thin-film transistor, wherein the switching thin-film transistor and the driving thin-film transistor together include: a lower conductive layer on the substrate; an insulation layer having therein a contact hole configured to expose the lower conductive layer; an upper conductive layer connected to the lower conductive layer through the contact hole; and a mask conductive layer between an upper surface of the insulation layer and the upper conductive layer to overlap the upper conductive layer.
