Abstract
The invention relates to a passive matrix-driven display based on electroluminescent polymers having a structured matrix of pixels and a structured second electrode with electrode connectors, having the following features: the functional polymers are delimited by windows of an insulating layer and contact a first electrode structured in the shape of strips and a second electrode, running parallel to the first electrode and also strip-shaped, which is in contact with electrode connectors; additional windows are disposed in the insulating layer and are positioned over the electrode connectors for the second electrode, or areas of the insulating layer are disposed between the electrode connectors; an encapsulation is provided that covers the insulating layer with the functional polymers and the second electrode, but leaves one end of each electrode connector exposed.
