Abstract: In an organic light-emitting display apparatus in which color mixing is reduced, the organic light-emitting display apparatus includes a substrate, a plurality of pixel electrodes disposed on the substrate to be apart from each other, a pixel defining layer disposed on the substrate and covering an edge of each of the plurality of pixel electrodes to expose a center portion of each of the plurality of pixel electrodes, and a plurality of spacers disposed on the pixel defining layer to be apart from each other, in which a distance between an edge of each of the plurality of spacers in a direction toward a closest pixel electrode and a portion or the closest pixel electrode that is not covered by the pixel defining layer is about 3 μm or less.

Abstract: A display apparatus includes a substrate having a first transmissive area, a second transmissive area, a pixel area between the first transmissive area and the second transmissive area, a first pixel electrode in the pixel area, a first intermediate layer disposed on the first pixel electrode to emit light of a first color and an insulating layer covering edges of the first pixel electrode and defining a first emission area through a first opening exposing a portion of the first pixel electrode. A first partition wall is disposed on the insulating layer between the first emission area and the first transmissive area. A second partition wall is disposed on the insulating layer between the first emission area and the second transmissive area. An opposite electrode is disposed on the first intermediate layer in the pixel area and partially contacts the first partition wall and the second partition wall.
