ORGANIC LIGHT EMITTING DIODE AND A FLAT DISPLAY DEVICE COMPRISING THE SAME CAPABLE OF REDUCING THE INTERFACE RESISTANCE OF AN ORGANIC LAYER AND AN ELECTRODE

摘要

PURPOSE: An organic light emitting diode and a flat display device comprising the same are provided to extend lifetime by reducing the resistance of a bulk.;CONSTITUTION: A light emitting layer(16) is formed between a first electrode(11) and a second electrode(19). A second hole-transport layer(15) includes a first hole-transport layer(13) and a second hole-transport compound. An electron-transport layer(17) is formed between the light emitting layer and the second electrode. A first mixing layer(12) is formed between the first electrode and the first hole-transport layer. A second mixing layer(14) is formed between the first electrode and the second hole-transport layer.;COPYRIGHT KIPO 2013
