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.
