1. A light emitting device comprising:
a substrate, having an electric accumulation layer that accumulates electric charge, wherein the electric accumulation layer is a first part of a resonant circuit in which resonance occurs; and
a light emitting element that is a second part of the resonant circuit coupled to the first part of the resonant circuit, wherein the light emitting element emits light in a case where a current in the resonant circuit is supplied,
wherein
the resonant circuit is not provided with an electric accumulation element other than the electric accumulation layer and having a thickness larger than a thickness of the electric accumulation layer.
