An object is to provide a light-emitting element and a light-emitting device each of which consumes less power and has high emission efficiency, high performance, and high reliability. A light-emitting element has an EL layer provided with a light-emitting layer, which includes an inorganic light-emitting material containing a mixed-valence compound, between a pair of electrode layers. When an element in a given 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. The mixed-valence compound affects charge mobility and emission color, and a light-emitting device having such a light-emitting element consumes less power, has high reliability and high image quality, and emits various colors of light. |
