This abstract first appeared for US patent application 18989228 titled 'LIGHT-EMITTING ELEMENT AND LIGHT-EMITTING DEVICE

Original Abstract Submitted

A light-emitting element includes: a first electrode serving as an anode; a second electrode serving as a cathode; a light-emitting layer, of a first wavelength range, provided between the first electrode and the second electrode; an oxide layer provided between the light-emitting layer of the first wavelength range and the first electrode of the first electrode and the second electrode; and an oxide layer provided between the oxide layer and the second electrode, and having contact with the oxide layer. Either the oxide layer or the oxide layer whichever farther away from the light-emitting layer of the first wavelength range is made of a semiconductor. A density of oxygen atoms in the oxide layer is lower than a density of oxygen atoms in the oxide layer.
