Abstract
An organic electroluminescent element comprising an anode, a cathode and a plurality of organic compound layers sandwiched between the anode and cathode, the organic compound layers including: a hole-transporting layer made of an organic compound insoluble in alcohols; and an electron-transporting layer formed on the hole-transporting layer by a wet method, the electron-transporting layer being made of a phosphorus-containing organic compound soluble in the alcohols.
