Abstract
Disclosed are compositions for an organic electroluminescent device favorably used for forming a hole injection layer and a hole transport layer of the organic electroluminescent device by a wet film forming method. The compositions for the organic electroluminescent device, which are composite solutions prepared by dissolving hole transport materials such as aromatic diamine compounds and an electron acceptor such as tri(pentafluorophenyl)boron in a solvent that contains an ether solvent and/or an ester solvent whose water solubility at 25° C. is 1 weight % or less in the solvent, with a concentration of 10 weight % or higher in the compositions.
