Abstract
Official abstract text for this publication.
An organic light-emitting display apparatus includes a substrate, an inorganic insulation film on the substrate, an organic insulation film on the inorganic insulation film, an organic light-emitting device on the organic insulation film, and an encapsulation unit including a first inorganic film covering the organic light-emitting device and having a first boundary portion contacting the organic insulation film, an organic film covering the first inorganic film and having a second boundary portion contacting the inorganic insulation film, and a second inorganic film covering the organic film and having a third boundary portion contacting the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. An organic light-emitting display apparatus comprising: a substrate; an inorganic insulation film on the substrate; an organic insulation film on the inorganic insulation film; an organic light-emitting device on the organic insulation film; and an encapsulation unit comprising: a first inorganic film covering the organic light-emitting device and having a first boundary portion contacting the organic insulation film; an organic film covering the first inorganic film and having a second boundary portion directly contacting a first side of the inorganic insulation film; and a second inorganic film covering the organic film and having a third boundary portion directly contacting the substrate, wherein a distal end of the first inorganic film is coplanar with a distal end of the organic insulation film; and wherein a distal end of the organic film is coplanar with a distal end of the inorganic insulation film, the distal end of the inorganic insulation film being a second side extending from the first side in a direction towards the substrate. 2. The organic light-emitting display apparatus of claim 1 , wherein the organic insulation film has an area that is smaller than an area of the inorganic insulation film. 3. The organic light-emitting display apparatus of claim 1 , wherein the first inorganic film has an area that is smaller than that of the organic film, and wherein the organic film has an area that is smaller than that of the second inorganic film. 4. The organic light-emitting display apparatus of claim 1 , wherein the organic insulation film comprises an upper surface having a portion on which the organic light-emitting device is not located, and wherein the first inorganic film contacts the upper surface of the organic insulation film, and does not contact the distal end of the organic insulation film. 5. The organic light-emitting display apparatus of claim 4 , wherein the distal end of the organic insulation film contacts the organic film. 6. An organic light-emitting display apparatus comprising: a substrate: an inorganic insulation film on the substrate; an organic insulation film on the inorganic insulation film; an organic light-emitting device on the organic insulation film; and an encapsulation unit comprising: a first inorganic film covering the organic light-emitting device and having a first boundary portion contacting the organic insulation film; an organic film covering the first inorganic film and having a second boundary portion directly contacting the inorganic insulation film; and a second inorganic film covering the organic film and having a third boundary portion directly contacting the inorganic insulation film; and wherein a distal end of the first inorganic film is coplanar with a distal end of the organic insulation film; wherein a distal end of the organic film is coplanar with a distal end of the inorganic insulation film; wherein the inorganic insulation film comprises the distal end and an upper surface, and wherein the organic film contacts the upper surface of the inorganic insulation film, and does not contact the distal end of the inorganic insulation film. 7. The organic light-emitting display apparatus of claim 6 , wherein the distal end of the inorganic insulation film contacts the second inorganic film.
