ABSTRACT:
A method of producing an organic electroluminescent element may include forming a transparent electrode as an anode on a transparent substrate; forming a light emission layer on the transparent substrate having thereon the anode; and forming a cathode on the substrate having thereon the anode and the light emission layer. The light emission layer may be formed by a method including arranging at least one vaporization crucible E evaporating a light emission dopant and at least one vaporization crucible I evaporating a host material and an intermediate layer forming material; and moving the substrate having thereon the anode over the vaporization crucibles E and I to form a light emission layer.
