    摘要： [It is an object] to provide an organic electroluminescent element with which the initial durability of the element can be greatly improved while maintaining the efficiency of the element at a high level. This is an organic electroluminescent element having an anode, a hole injection layer, a first hole transport layer, a second hole transport layer, a light-emitting layer, and a cathode, in this order, with this organic electroluminescent element being such that the aforementioned hole injection layer includes a material for which the energy of the lowest unoccupied molecular orbital (LUMO) is less than −4.0 eV and also such that the energy E1(LUMO) of the LUMO of the material included in the aforementioned first hole transport layer and the energy E2(LUMO) of the LUMO of the material included in the aforementioned second hole transport layer satisfy [the inequality] E1(LUMO)>E2(LUMO).

    摘要： High light transmission efficiency is achieved in an electroluminescence device without lowering the durability of the device. The electroluminescence device includes: electrodes; a plurality of layers that are deposited one on another between the electrodes; and a light emitting region between the plurality of layers. The light emitting region emits light by application of an electric field between the electrodes. At least one microparticle that induces plasmon resonance on the surface thereof by the light emitted from the light emitting region is arranged in the vicinity of the light emitting region or in the light emitting region. The microparticle is a core-shell-type microparticle including at least one metal microparticle core and an insulation shell that covers the at least one metal microparticle core.
