Abstract:
A full color organic electroluminescent display device comprising:a substrate element;a plurality of thin film transistors, formed on the substrate element;a planarizing layer of a dielectric material positioned over the plurality of thin film transistors and defining a substantially planar surface;a plurality of contact pads formed on the planar surface of the planarizing layer, one contact pad associated with each thin film transistor of the plurality of thin film transistors and coupled to the associated thin film transistor by an opening through the planarizing layer;at least one layer of organic material sequentially formed in overlying relationship on the contact pads so as to define an organic light emitting device on each contact pad with each contact pad operating as a first terminal of an overlying organic light emitting device; andelectrical and light conducting material positioned in overlying relationship over the at least one layer of organic material and operating as a common second terminal of the organic light emitting devices.
