| 摘要 |
An organic electroluminescent device has transparent substrate (1), anode (2) containing a metal oxide, such as indium-tin oxide or indium-zinc oxide as a major component, an organic electroluminescent layer, which may be composed of hole injection layer (3), hole transport layer (4), light-emitting layer (5), and cathode (6). The anode (2) is subjected to nitrogen oxide (e.g. NO<SB>2</SB>) decoration after deposition on substrate (1), which improves filling rate, adhesivity and thermal stability at the interface between the anode (2) and hole injection layer (3), resulting in lower driving voltage and longer lifetimes in the device. The construction may include seal-off plate (7). The electroluminescent layer may include a layer containing a phthalocyanine compound as a major component. |
