Abstract:
An electroluminescent display device comprisinga light emitting layer having a first and a second surface on opposite sides of the layer, an electrode assembly in contact with and on one side of the first surface of said light emitting layer, a transparent conductive layer in contact with said second surface and on a side of said light emitting layer opposite from the electrode assembly, said electrode assembly comprising a plurality of first line patterned electrodes, a plurality of second line patterned electrodes, a plurality of first sub-pixel electrodes adjacent to the second line patterned electrodes, a first insulating layer, separating the first and second line patterned electrodes, a plurality of first vias, each via extending from at least one of said first sub-pixel electrodes through the said insulating layer, to one of said first line patterned electrodes, a plurality of second sub-pixel electrodes adjacent to the first sub-pixel electrodes, a second insulating layer separating the first and second sub-pixel electrodes from the second line patterned electrodes, and a plurality of second vias, each via extending from at least one of said second sub-pixel electrodes through the said insulating layers, to one of said second line patterned electrodes.
