Abstract

The invention relates to a lighting device comprising an illuminant embodied as an OLED, and comprising a capacitive switching means, which are arranged on a substrate, wherein the illuminant has a first electrically conductive electrode and a second electrically conductive electrode, wherein a layer comprising organic, electroluminescent material is arranged between the first electrode and the second electrode, wherein the switching means has an electrode, wherein one electrode from the first electrode or the second electrode of the illuminant together with the electrode of the switching means is arranged in one plane, wherein a nonconductive spacing amounting to between 100 μm and 700 μm, more particularly between 400 μm and 600 μm, is present between said one electrode of the illuminant and the electrode of the switching means in the plane.
