Organic light-emitting device

摘要

An organic EL light emitter is disclosed that can emit white light without an increase in driving voltage. The organic EL light emitter has a substrate, a reflecting electrode, and a plurality of layers comprising organic EL layers and transparent electrodes formed alternately on the reflecting electrode. The reflecting electrode is in contact with one of the organic EL layers, and each of the organic EL layers emits light of a different color. The reflecting electrode and the even numbered ones of the transparent electrodes counting from the reflecting electrode side have the same polarity as one another, while the odd numbered ones of the transparent electrodes counting from the reflecting electrode side have a polarity that is the opposite that of the reflecting electrode and the even numbered electrodes.
