Patent ID: 7923920

Claim:
An organic light-emitting device, comprising: a substrate; and a plurality of organic light-emitting elements formed on the substrate, wherein the plurality of the organic light-emitting elements include a first organic light-emitting element which emits a light of a first emission color, and a second organic light-emitting element which emits a light of a second emission color different from the first emission color, wherein each of the organic light-emitting elements has a first electrode, an organic compound layer containing a light-emitting layer, and a second electrode in this order on the substrate, wherein the first electrode of both the first and second organic light-emitting elements has a light reflection layer and a first transparent conductive layer; wherein the light reflection layer of the first organic light-emitting element is formed between the substrate and the first transparent conductive layer of the first organic light-emitting element, wherein the light reflection layer of the second organic light-emitting element is formed between the first transparent conductive layer of the second organic light-emitting element and the organic compound layer of the second organic light-emitting element, and wherein a thickness of the first transparent conductive layer of the first organic light-emitting element is the same as a thickness of the first transparent conductive layer of the second organic light-emitting element.
