Abstract
The object of the present invention is to provide an organic light emitting device which can be operated at a low voltage, and when such elements are used in a display panel, a light-emitting surface which can emit light uniformly over an entire display panel can be obtained when the conditions are maintained the same. The organic light-emitting device of the present invention includes a substrate having a light transmitting property in a visible range, a first electrode having a light transmitting property in a visible range, and formed on the substrate, a layer formed on the first electrode, and configured to emit light by recombination of excitons each made of a pair of a positive hole and electron injected thereto, and a second electrode containing erbium and formed on the layer.
