ORGANIC ELECTROLUMINESCENCE DEVICE, CONDUCTIVE LAMINATE AND DISPLAY

摘要

An organic electroluminescence device comprising negative electrode (50), positive electrode (20) and luminescent layer (40) interposed between the negative electrode (50) and the positive electrode (20), wherein at least part of the positive electrode (20) in contact with the luminescent layer (40) contains at least one element selected from among lanthanum, cerium, neodymium, samarium and europium and at least one element selected from among chromium, tungsten, tantalum, niobium, silver, palladium, copper, nickel, cobalt, molybdenum, platinum and silicon. This device, as efficient hole injection from the positive electrode into the luminescent layer can be carried out, can realize further lowering of driving voltage of organic EL device and operating life prolongation owing to low-voltage driving.
