Patent ID: 7622865

Claim:
A light-emitting device comprising: a substrate; a light reflection layer that is formed on the substrate and reflects light; a first electrode that is formed on the light reflection layer and transmits light; a light-emitting layer that is formed on the first electrode and emits light; a second electrode that is formed on the light-emitting layer and transmits a part of light from the light-emitting layer and reflects the rest of the light from the light-emitting layer; and a conductive transflective layer that is formed on the second electrode and that transmits a part of light from the second electrode and reflects the rest of the light from the second electrode, wherein a work function of the second electrode is 4 eV (electron volts) or less, and the conductive transflective layer is formed of a metal material having a higher optical reflectance than the second electrode.
