Beschreibung
Zusammenfassung:A transparent thin film display element (100) with a display region(101), and a transition region (105) having a first edge (106) bordering the display region and a second edge (107) opposite to the first edge, the transparent display element having a layer stack (103) comprises:a first conductor layer (110); a second conductor layer (120); and an emissive layer (130) superposed between the first and the second conductor layers and configured to emit light upon electrical current flowing through the emissive layer between the first and the second conductor layers. At least one layer (120) of a group comprising the first and the second conductor layers and the emissive layer has, in the transition region (105), a first coverage at the first edge (106), a second coverage lower than the first coverage at the second edge (107), and an intermediate coverage lying between the first and the second coverage.
