    Abstract: A method of manufacturing an organic light-emitting display apparatus includes: forming a pixel electrode on a substrate; forming a pixel-defining layer (PDL) having an opening exposing at least a part of the pixel electrode; forming an intermediate layer including a central portion disposed on the pixel electrode, an edge portion that extends from the central portion and contacts the PDL, at least one common layer, and an organic emission layer; forming a protective layer including a central portion disposed on the central portion of the intermediate layer and an edge portion that extends from the central portion of the protective layer and contacts the PDL; and forming an opposite electrode on the PDL, the opposite electrode having an opening exposing at least a part of the protective layer and electrically connected to the protective layer.

    Abstract: A display device includes: a substrate including a first pixel area (PA) and a second PA, the first PA being spaced apart from the second PA by a non-PA; a first pixel electrode (PE) overlapping the first PA; a second PE overlapping the second PA; a pixel-defining layer including a first opening overlapping the first PE and a second opening overlapping the second PE; a first intermediate layer (IL) on the first PE, the first IL including a first emission layer (EL); a second IL on the second PE, the second IL including a second EL spaced apart from the first EL; a first opposite electrode (OE) on the first IL; a second OE on the second IL, the second OE being spaced apart from the first OE; and a wiring layer (WL) overlapping the non-PA, the WL contacting respective portions of the first OE and the second OE.

    Abstract: An organic light-emitting display device includes a substrate including a display area and a peripheral area surrounding the display area. The display area includes a plurality of pixel regions including a plurality of pixels including pixel electrodes and non-pixel regions between the pixel regions. The pixel electrodes are spaced apart from each other, with a pixel-defining layer above the plurality of pixel electrodes and exposing the plurality of pixel electrodes. A plurality of intermediate layers respectively above the plurality of pixel electrodes include an emission layer. A plurality of opposite electrodes respectively face the plurality of pixel electrodes and are spaced apart from each other. A plurality of connection electrodes that connect the plurality of opposite electrodes are in the non-pixel regions. A power line electrically connected to at least one of the plurality of connection electrodes is in the peripheral area.

    Abstract: A display device including a first pixel electrode and a second pixel electrode disposed adjacent to each other on a substrate; a pixel defining layer including a first opening corresponding to the first pixel electrode, a second opening corresponding to the second pixel electrode, and a first convex portion arranged adjacent to the first opening; a first intermediate layer arranged on the first pixel electrode to correspond to the first opening and including a first emission layer; and a first conductive inorganic layer arranged on the first intermediate layer to correspond to the first opening. At least one end of the first conductive inorganic layer extends beyond an end of the first intermediate layer and is disposed on the pixel defining layer between the first opening and the second opening.
