| 摘要 |
The invention relates to an organic electroluminescent device (1) comprising a substrate (2), at least one electroluminescent layer stack on top of the substrate (2) with at least a substrate electrode (3), a counter electrode (5) and at least one organic electroluminescent layer (4) arranged between substrate electrode (2) and counter electrode (5), and a short prevention layer (6) covering the counter electrode (5) establishing a double layer (DL) with a tensile stress (TS) induced by the short prevention layer (5), and an electrically isolating layer (8) at least partly covering the short prevention layer (6), wherein the electrically isolating layer (8) is suitable to partially dissolve the organic layer (4) in the vicinity of a defect (7) within the electroluminescent layer stack and the tensile stress (TS) induced by the short prevention layer (6) is suitable to roll up (10) the double layer (DL) adjacent to the defect (7) after deposition of the electrically isolating layer (8). The invention further relates to a method to manufacture such OLED devices (1) and the use of a short prevention layer (6) to prevent shorts in such OLED devices (1).
