| 摘要 |
The invention provides an organic EL device comprising a hole injecting electrode, and at least one organic layer disposed between the electrodes, wherein the electron injecting electrode is comprised of an AlLi alloy containing 0.4-14 at % of lithium deposited by a sputtering process. This improves the film formability and adhesion at the interface between the electron injecting electrode and the organic layer, realizing an organic EL device featuring a high luminance, high efficiency, long lifetime, and high display quality.
