ABSTRACT:
In an organic EL device comprising a cathode, an anode, and two or more stacked organic layers therebetween including a light emitting layer, an electron injecting organic layer containing an organic salt or complex of a metal having a standard electrode potential of more negative than −1.8 V at 25° C. is formed close to the cathode by coating, and an organic layer containing a high molecular weight EL material is disposed close to the electron injecting organic layer. A multilayer structure of organic layers can be formed by coating, and the organic EL device has a high luminance, high efficiency, high reliability, long life and ease of handling.
