Electroluminescent display

Abstract

There is disclosed an electroluminescent (EL) device accomplishing improved visual performance. The device has a transparent substrate on which a transparent electrode layer is formed. The transparent electrode layer is partitioned into segments to represent desired shapes in terms of pixels by selective emission of the segments. Parts of the transparent electrode layer are brought out toward the outer periphery of the transparent substrate to form terminals. Display electrodes, the terminals, and conductive interconnects that are different in function are formed from the transparent electrode layer. The conductive interconnects connect the display electrodes with the terminals. Other terminals for connection with a back electrode are also formed from the transparent electrode layer. An auxiliary electrode layer having a resistivity smaller than that of the transparent electrode layer is formed on the transparent electrode layer. An intermediate dielectric layer is formed over the transparent electrode layer except for locations where the display electrodes and the first-mentioned terminals are present. An emissive layer is formed on the display electrodes and on the dielectric layer. The back electrode is formed over the emissive layer and located opposite to the display electrodes.
