Patent ID: 8471943

Claim:
A stacked organic light-emitting element, comprising: a first organic compound layer; a second organic compound layer; a third organic compound layer; and a common transparent electrode, the first organic compound layer, the second organic compound layer, and the third organic compound layer having emission colors different from each other and directly contacting the common transparent electrode, wherein the first organic compound layer and the second organic compound layer are stacked via the common transparent electrode, wherein the first organic compound layer and the third organic compound layer are stacked via the common transparent electrode, wherein the first organic compound layer, the second organic compound layer, and the third organic compound layer separately emit light, wherein the first organic compound layer has a polarity direction opposite to a polarity direction of the second organic compound layer, wherein the first organic compound layer has the polarity direction opposite to a polarity direction of the third organic compound layer, and wherein the first organic compound layer, the second organic compound layer and the third organic compound layer each have functional layers including a light-emitting layer, a hole transport layer and an electron transport layer, and wherein in a direction in which the first organic compound layer and the second organic compound layer are stacked, the stacking order of the functional layers of the first organic compound layer and the stacking order of the functional layers of the second organic compound layer are reverse to each other, and the stacking order of the functional layers of the first organic compound layer and the stacking order of the functional layers of the third organic compound layer are reverse to each other.
