Disclosed is an organic electroluminescent element having an element structure that can reduce damage to an organic layer during electrode formation and can facilitate the injection of charges from the electrode into the organic layer. The organic electroluminescent element includes an anode, a cathode, and an organic layer held between the anode and the cathode. The organic layer contains a luminescent material. The organic electroluminescent element further includes a transparent protective layer provided between the anode or the cathode and the organic layer. The transparent protective layer contains a bipolar charge transport organic compound and an electron-accepting compound. The transparent protective layer is formed in a period between after the formation of the organic layer and before the formation of the anode or the cathode on the organic layer.

The present invention provides a flexible substrate, which has solvent resistance, a high level of gas barrier properties, a high level of flexibility, high heat resistance, and a high level of transparency, and is suitable, for example, for use in a wet coating process of an organic device material, and an organic device using the same. The flexible substrate comprises a metal oxide polymer-containing layer and a three-dimensionally crosslinked polymer layer stacked in that order on at least one side of a very thin glass. The metal oxide polymer is a silicon oxide polymer, and the metal oxide polymer-containing layer underlying the three-dimensionally crosslinked polymer layer is neither swollen nor dissolved in an aromatic organic solvent.
