发明名称 ORGANIC ELECTROLUMINESCENCE DEVICE HAVING CURRENT INJECTION LAYER BETWEEN LIGHT EMITTING LAYER AND CATHODE
摘要 Provided is an organic electroluminescence device which operates at a low voltage, has a uniform light emission surface, and can display high-quality images. In an organic electroluminescence device, an anode (2), a hole transport layer (3) made of an organic compound, a light emitting layer (4) made of an organic compound, and a cathode (6) are stacked in the order named, and an electron injection layer (5) containing a lanthanoid oxide is formed between the light emitting layer and cathode. The anode (2) and/or cathode (6) is made of a transparent conductive material. In another organic electroluminescence device, an anode (2), a hole transport layer (3) made of an organic compound, a light emitting layer (4) made of an organic compound, and a cathode (6) are stacked in the order named, and an electron injection layer (5) formed by mixing a lanthanoid metal oxide and organic compound is formed between the light emitting layer and cathode. <IMAGE>
