    Abstract: A display device includes a lower substrate, a planarization layer, a first light emission structure, and a second light emission structure. The lower substrate includes a first region and a second region. The planarization layer is disposed on the lower substrate, and has a first thickness in the first region and a second thickness, which is less than the first thickness, in the second region. The first light emission structure is provided in the first region and arranged on the planarization layer, and emits a first color of light. The second light emission structure is provided in the second region and arranged on the planarization layer, and emits the first color of light.

    Abstract: An organic light-emitting display device including a plurality of pixels, each of which includes an organic light-emitting device including a pixel electrode, an organic emission layer, and an opposing electrode; a pixel defining layer covering an edge of the pixel electrode and being configured to define a light-emission region by having an opening which exposes a portion of the pixel electrode; and a reference line overlapping the pixel electrode with an insulating layer between the reference line and the pixel electrode and extending in a first direction. The reference line overlaps with a center point of the opening, and the opening is shifted to one side of the pixel electrode in a second direction perpendicular to the first direction.

    Abstract: An OLED display device includes a substrate, a first protection layer substrate, conductive lines extending substantially in a first direction, a second protection layer, a first electrode overlapping at least a part of the conductive lines, a pixel defining layer including an opening exposing at least a part of the first electrode, an organic light emission layer, and a second electrode. The opening is divided into a first polygon and a second polygon with respect to an imaginary straight line that passes through the opening at a maximum length in the first direction. A planar area of the first polygon is different from a planar area of the second polygon.
