Abstract
An organic light-emitting device has a substrate and a plurality of organic light-emitting elements formed on the substrate. The plurality of the organic light-emitting elements include a first light-emitting element emitting light of a first emission color, and a second light-emitting element emitting light of a different emission color. Each light-emitting element has, in sequence, a first electrode having a light reflection layer and a transparent conductive layer, an organic compound layer containing a light-emitting layer, and a second electrode on the substrate. The light reflection layer of the first element is between the substrate and the transparent conductive layer and the light reflection layer of the second element is between the transparent conductive layer and the organic compound layer. A thickness of the transparent conductive layer of the first and second organic light-emitting elements is the same.
