LIGHT-EMITTING ELEMENT AND LIGHT-EMITTING DEVICE |
摘要 |
An object is to provide a highly functional and reliable light-emitting element and light-emitting device with lower power consumption and high emission efficiency. The light-emitting element has an EL layer that has a stacked structure including a light-emitting element containing an organic compound and a functional layer having separate functions between a pair of electrode layers. In the light-emitting element including the functional layer and the light-emitting element containing an organic compound, a mixed-valence compound is contained in the functional layers. When an element in a compound has a plurality of valences, this element is in a state that is referred to as a mixed-valence state and this compound is referred to as a mixed-valence compound.
