The invention describes an OLED device () comprising an organic layer () which emits light (L) in operation and which is positioned between an essentially transparent anode layer () and an essentially opaque cathode layer (). The cathode layer () is deliberately structured along a main extension plane (EP) of the OLED device to comprise at least one cathode region () in which the cathode layer () is 10 present and a plurality of cathode-free regions () and/or at least one cathode-free region () of a larger extension, through which cathode-free regions and/or region () visible light (L) can pass in the direction of a cross extension (CE) of the OLED device. The invention also describes a production method of such OLED device ().
