Abstract
An organic light-emitting device includes, in order an anode, an organic layer comprising a light-emitting layer, and a cathode. The anode is a laminated structure comprising in order: a first anode layer comprising a metal compound or a conductive oxide; a second anode layer that is a reflective layer; and a third anode layer comprising a metal compound or a conductive oxide. Light generated in the light-emitting layer is extracted through the cathode.
