Abstract
The invention describes a passive-matrix powered display with structured pixels and a structured second electrode based on electroluminescent polymers with the following characteristics: functional polymer coatings, which contact a first electrode, are enclosed by windows of an insulating window coating, at least one additional insulating striped coating, which is located between the windows of the first insulating coating, is located across from the first electrode strips as a partition, a second electrode that contacts the functional coatings is structured through partitions and runs across toward the first electrode strips between the partitions.
