Electrode substrate for an optoelectronic device having a fabric () that includes electrically conductive () as well as non-conductive () and transparent fibers wherein the fabric is furnished over a wide area with a transparent, electrically conductive coating () in such manner that projecting or exposed portions of the electrically conductive fibers cooperate with the conductive coating in order to produce electrical contacts, wherein the conductive coating has a layer thickness that is smaller than a mean diameter of the electrically conductive and electrically non-conductive fibers of the fabric, a fabric weave of the electrically conductive fibers of the fabric is organized in such a manner that in order to create the protruding portions, the fibers encompass at least 2 of the non-conductive fibers that extend transversely in the manner of a twill weave, the fabric is embedded in the coating in such manner that portions () of the conductive fibers protrude from a non-conducting polymer material of the coating and/or are exposed, at least on one side of the coating, and the coating is applied to a polymeric, electrically non-conductive and transparent carrier film that is situated opposite the conductive coating that is applied to one side relative to the fabric.

Electrode substrate and planar optoelectronic device

An optoelectronic film assembly, has a first flat electrode layer, a second flat electrode layer as a counter electrode to the first flat electrode layer, a dielectric layer between the electrode layers and an active layer provided next to the dielectric layer and arranged between the electrode layers and made of an electroluminescent material. To this end, the first and/or the second electrode layers are implemented to be translucent and TCO-free, particularly ITO-free, by using a woven fabric comprising electrically conductive fibers.
