摘要

PROBLEM TO BE SOLVED: To provide an organic EL element in which light emission characteristics are not easily deteriorated even when driven continuously, and a method of manufacturing the same.;SOLUTION: A organic electroluminescent element 10 includes: a light emitting layer 6 between a cathode 3 and an anode 9; and an electron injection layer 1 containing, between the cathode 3 and the light emitting layer 6, one or more elements selected from tin, zirconium, silicon, germanium, titanium, and hafnium, and zinc oxide nanoparticles. The average particle size of the zinc oxide nanoparticles is preferably 1 to 500 nm.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
