Abstract: A display device can include a substrate including first and second pixel regions; a first electrode in each of the first and second pixel regions; and a bank disposed at a boundary of each of the first and second pixel regions on the first electrode defining a first opening exposing a portion of the first electrode and a second opening within the bank defining a formation area of an emitting layer, the second opening is larger than the first opening, in which an area of the first opening in the first pixel region is smaller than an area of the first opening in the second pixel region, and an area of the second opening in the first pixel region is substantially same as an area of the second opening in the second pixel region.
