Abstract: 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.
