Patent ID: 7327081

Claim:
A stacked organic electroluminescent device, comprising: a substrate, having a first luminescent region, a second luminescent region, and a third luminescent region; an anode layer, disposed above the substrate; a first organic emitting layer, disposed above the anode layer; a second organic emitting layer, disposed above the first organic emitting layer; a third organic emitting layer, disposed above the second organic emitting layer; a first carrier generation layer, disposed between the first organic emitting layer and the second organic emitting layer; a second carrier generation layer, disposed between the second organic emitting layer and the third organic emitting layer; a first reflecting layer, disposed in the first emitting region and between the substrate and the first organic emitting layer; a second reflecting layer, disposed in the second emitting region and between the first organic emitting layer and the second organic emitting layer; a third reflecting layer, disposed in the third emitting region and between the second organic emitting layer and the third organic emitting layer; and a cathode layer, disposed above the third organic emitting layer.
