Claim Text:
1. An organic electroluminescence device comprising: a substrate; a first electrode layer formed on the substrate; a layer of organic electroluminescence material formed on the first electrode layer; a second electrode layer formed on the layer of organic electroluminescence material; a cover layer being positioned on a side of the second electrode layer that faces away from the layer of organic electroluminescence material; a moisture-absorbing layer; and a separating foil of resilient material formed on a surface of the second electrode layer, said separating foil being positioned between the second electrode layer and the moisture-absorbing layer; and a plurality of spacer structures, said plurality of spacer structures being positioned between the separating foil, and one of the moisture-absorbing layer and the cover layer, wherein a first surface of the plurality of spacer structures is fixed on a surface of the separating foil which faces towards the moisture-absorbing layer, wherein a second surface of the plurality of spacer structures is fixed on one of a surface of the moisture-absorbing layer which faces towards the separating foil and a surface of the cover layer which faces towards the separating foil, wherein the plurality of spacer structures are primarily composed of a cured adhesive material, and wherein a contact ratio is between 5% and 20%, the contact ratio being a total surface area of the separating foil covered by the plurality of spacer structures divided by a total surface area of the separating foil.
