ORGANIC ELECTRIC FIELD EMITTING DEVICE HAVING A HIGH EMITTING EFFICIENCY, A HIGH QUANTUM EFFICIENCY AND A LOW DRIVING VOLTAGE

摘要

PURPOSE: An organic electric field emitting device is provided to improve a color stability of a blue by only including a blue emitting layer to a first stack.;CONSTITUTION: A first stack is located on an anode electrode(120). The first stack(130) has a first emitting layer. The first emitting layer includes a fluorescence blue dopant. A charge generating layer(140) is located on the first stack. A second stack(150) is located on the charge generating layer. The second stack has a second emitting layer and a third emitting layer. The second emitting layer and the third emitting layer include a fluorescent green and a red dopant. A cathode electrode(160) is located on the second stack.;COPYRIGHT KIPO 2010
