Abstract: An organic electroluminescence element includes an anode, a light-emitting layer disposed over the anode, a functional layer disposed on the light-emitting layer in contact with the light-emitting layer and including a first metal, a light-transmitting conductive layer disposed on the functional layer in contact with the functional layer and composed of a metallic oxide, and a cathode disposed on the light-transmitting conductive layer in contact with the light-transmitting conductive layer and composed of a metal. The functional layer has a film thickness of 15 to 35 nm. A surface of the anode on the light-emitting layer side and an interface between the cathode and the light-transmitting conductive layer are spaced from each other by not less than 150 nm.

Abstract: An organic EL element includes an anode, a light emitting layer, a functional layer, a cathode, and a low refractive index layer. The light emitting layer is disposed above the anode. The functional layer is disposed on and in contact with the light emitting layer and includes a first metal. The cathode is disposed on and in contact with the functional layer and is made of a light transmissive metal oxide. The low refractive index layer is disposed on and in contact with the cathode. Refractive index of the low refractive index layer is smaller than refractive index of the cathode, film thickness of the functional layer is from 15 nm to 35 nm, and a distance between an anode-side surface of the light emitting layer and an interface between the cathode and the low refractive index layer is 110 nm or greater.

Abstract: Light emitters are two-dimensionally disposed along a main surface of the substrate. The light emitters each include: a first electrode; an organic light-emitting layer; an intermediate layer; a charge transport layer; and a second electrode. Such layers are disposed in the stated order with the first electrode closest to the substrate. The intermediate layer contains a fluoride of an alkali metal or a fluoride of an alkaline earth metal. The charge transport layer contains an organic material doped with an alkali metal or an alkaline earth metal. The light emitters are partitioned from one another by first banks extending in one direction along the main surface of the substrate and second banks extending in a direction intersecting the one direction. Surface portions of the first banks facing the light emitters have greater liquid repellency than surface portions of the second banks facing the light emitters.

Abstract: An organic electroluminescence (EL) element that has an anode; a cathode; an organic light-emitting layer between the anode and the cathode that emits light according to recombination of holes injected from the anode and electrons injected from the cathode; and an electron transport layer between the cathode and the organic light-emitting layer that transports electrons from the cathode to the organic light-emitting layer. The electron transport layer includes an n-type dopant that includes an electron-donating substance, the electron transport layer being doped with the n-type dopant at a doping concentration that is higher than a doping concentration at which light emittance efficiency of the organic light-emitting layer is greatest.
