Electroluminescent display having increased luminescent area

摘要

An EL display comprises a transparent substrate and a first electrode layer made of a transparent material disposed on the transparent substrate. A luminescent layer, a first insulation layer and a second electrode layer are disposed successively on a surface of the first electrode layer except for a preselected surface portion thereof defining an exposed portion. A second insulation layer is disposed on a surface of the second electrode layer except for a preselected surface portion thereof defining an exposed portion. A first contact layer is disposed on the exposed portion of the second electrode layer for electrical connection to an external driving control circuit. A second contact layer is disposed on the second insulation layer for electrical connection to the exposed portion of the first electrode layer and to the external driving control circuit.
