Organic electroluminescent element and display device

Abstract

An organic electroluminescent element, in which reduction in drive voltage is achieved, is provided. The organic electroluminescent element has an organic layer 20 between an anode 11 and a cathode 31, and the organic layer 20 has a structure where an n-doped layer 21, a hole transport layer 22, a light emitting layer 23, and an electron transport layer 24 are stacked in order from an anode 11 side. The n-doped layer 21 contains hexacyanohexaazatriphenylene and 4,4′,4″-tris(3-methylphenylphenylamino)triphenylamine. When an electric field is applied to the organic layer 20, holes from the anode 11 are efficiently sufficiently injected into the light emitting layer 23.
