Abstract:
1. A light emitting element comprising a first layer and a third layer and a second layer containing a light emitting material between a first electrode and a second electrode, wherein the first layer is provided in contact with the first electrode, and the first layer is formed from a composite material comprising organic compounds and an inorganic compound, wherein the first electrode forms an ohmic contact with the first layer, wherein the composite material is to have both band conduction using carrier generation by adding an electron-accepting material to the organic compound and hopping conduction between organic compounds when the organic compound transports carriers injected from outside, wherein the third layer is between the first layer and the second layer, wherein the organic compounds are an aromatic amine compound and rubrene, wherein the inorganic compound is a molybdenum oxide, and wherein the first electrode is an indium tin oxide layer to which silicon is added.
