摘要：
Provided is an organic electroluminescent member comprising: a positive electrode and a negative electrode on a substrate; multiple organic layers which include at least a positive hole transport layer, a light-emitting layer and an electron transport layer, and which are arranged between the positive electrode and the negative electrode; and an electron injection layer arranged between the electron transport layer and the negative electrode. The electron injection layer is formed from at least one selected from the group consisting of alkali metals and compounds containing alkali metals having melting point of less than 90° C., and at least one selected from the group consisting of alkali metals, alkaline earth metals, compounds containing alkali metals, and compounds containing
