Abstract
The invention relates to an OLED(1) comprising an etch stop layer (3) between a first electrode (2) and anorganic layer stack (4) and an electrically conductive element (13) arranged in an etched region (6) within a second electrode (5) and the organic layer stack such that the electrically conductive element is electrically connected with the first electrode. The etch stop layer is a hole-injection layer comprising a metal oxide with semi conducting properties. In particular, the OLED may comprise several electrically conductive elements in several etched regions, wherein the electrically conductive elements can be electrically connected with different parts of the first electrode and with each other via an electrical connector (14) for shunting the different parts of the first electrode, which can lead to a more homogenous light emission. The electrical conductive elements may also be used to provide a color tunability. The etch stop layer can reduce the likelihood of the first electrode to be damaged due to etching.
