The present invention provides an organic electroluminescence device capable of having not only a device lifetime comparable to that of an existing organic electroluminescence device but also a small thickness of smaller than 10 μm and excellent flexibility. The present invention relates to an organic electroluminescence device having a structure including: an anode; a cathode on a substrate; and a laminate of multiple layers between the anode and the cathode, the device having a thickness of smaller than 10 μm.

Organic electroluminescent element

The present invention provides an organic electroluminescence device having excellent luminous efficiency and excellent luminance. The present invention relates to an organic electroluminescence device including a structure in which a plurality of layers is laminated between an anode and a cathode formed on a substrate; wherein the organic electroluminescence device includes a metal oxide layer between the anode and the cathode; and a nitrogen-containing film layer having an average thickness of not less than 0.1 nm but less than 3 nm adjacent to the metal oxide layer and disposed on an anode side.

An organic thin film that imparts an excellent electron injection property when it is used as an electron injection layer of an organic EL device and a method for producing the organic thin film are provided. An organic thin film at least includes: a first material which is an organic material having an acid dissociation constant pKa of 1 or greater; and a second material which transports an electron. The first material is at least one selected from the group consisting of tertiary amines, phosphazene compounds, guanidine compounds, heterocyclic compounds containing an amidine structure, hydrocarbon compounds having a ring structure, and ketone compounds.
