Abstract

An organic electroluminescence device (OLED) has a substrate, a first electrode layer, a layer of organic electroluminescence material, a second electrode layer, a cover layer, a moisture-absorber and a separating foil of resilient material. The separating foil is positioned between the second electrode layer and the moisture-absorber. Spacer structures such as dots are applied on the separating foil between the foil and the cover.
