Abstract:
1. An organic light-emitting display apparatus comprising a substrate and having a plurality of subpixels on the substrate, the organic light-emitting display apparatus further comprising: a thin film transistor on the substrate; an organic light-emitting device electrically connected to the thin film transistor and in one of the subpixels, the organic light-emitting device comprising a first electrode, an organic layer on the first electrode, and a second electrode on the organic layer; a pixel defining layer having an opening that exposes a region of the first electrode, and covering an edge region of the first electrode to define an emission area of the one of the subpixels; a capping layer covering the organic light-emitting device; and at least one clamp unit next to the emission area of the one of the subpixels, wherein the at least one clamp unit is not formed on the organic layer, wherein a surface region of the pixel defining layer surrounds the one of the subpixels and is buried by the capping layer, wherein a gap exposing the surface region of the pixel defining layer is between the organic layer and the at least one clamp unit, and wherein the gap is filled with the capping layer so that the pixel defining layer and the capping layer directly contact each other.
