Abstract
In a coating-type electron injection layer or electron transport layer using a metal oxide, the present invention aims at improving uniformity or stability of composition distribution and adhesion with another adjoining constituent layer, and improving film forming property, to thereby provide an organic electronic device and manufacture of the device whose efficiency is improved. In the organic electronic device having one pair of electrodes on a substrate, and having at least one organic layer between the electrodes, the electron injection layer or the electron transport layer is formed by application of a liquid material in which an alkaline metal salt and zinc-oxide nano particles are dissolved in alcohol.
