  • White organic electroluminescent device
    Publication number: 20050100760
    Abstract: A white organic EL device has an organic layer between an anode and a cathode on a substrate. The organic layer has at least a blue emitting layer, a red emitting layer, and a green emitting layer. The red emitting layer contains a blue emitting compound doped with at least one of a yellow dopant dye 14b and a red dopant dye 14c. When a voltage is applied between the anode and the cathode, each emitting layer emits blue, red, and green light respectively, therefore the white organic EL device 20 emits white light.
