Organic electroluminescence device and method of producing the same

摘要

An organic EL device includes an anode layer, a hole injection and transport layer, an organic light-emitting layer and a cathode layer. The anode layer is formed of metal-oxide based material which is electrically conductive. The hole injection and transport layer is formed on the anode layer using material other than phthalocyanine metal complex. The organic light-emitting layer is formed on the hole injection and transport layer. The cathode layer is formed on the organic light-emitting layer. After the organic EL device is heated for 150 hours at the temperature of 85 °C, the retention rate of its power efficiency is equal to or more than 80 %.
