摘要：
The invention pertains to an organic light emitting diode (LED) comprising a transparent electrode, superposed by a layer of a conductive transparent polymer (CTP), superposed by a layer of a light emitting polymer, oligomer, or low molecular weight compound superposed by a metal cathode, characterized in that the CTP layer has a sulfate ion content of less than 7,500 ppm, and a metal ion content of more than 0.04 mmoles/g.
