Abstract
A full color organic electroluminescent display device including a substrate element and a plurality of thin film transistors, formed on the substrate element. A planarizing layer of insulating material is positioned over the plurality of thin film transistors, thereby defining a substantially planar surface. A plurality of contact pads are formed on the planar surface of the planarizing layer, with one contact pad associated with each thin film transistor. A hole transporting layer is deposited over the contact pads. Three pixelated emissive organic electron transporting media are formed on a top surface of the hole transporting layer so as to define an organic light emitting device. An electrical and light conducting material is positioned in overlying relationship over the emissive organic electron transporting media, thereby operating as a common second terminal of the organic light emitting devices.
