Patent ID: 8299787

Claim:
A multicolor phosphorescence light emitting organic electroluminescent element comprising two or more phosphorescence light emitting dopants which emit emission lights each having a different emission wavelength from each other, and at least two light emitting layers, provided that all of the light emitting dopants are phosphorescence light emitting dopants, wherein one of the light emitting layers, designated as a light emitting layer A, contains the two or more phosphorescence light emitting dopants which emit the emission lights each having a different wavelength from each other in the same layer, provided that a content of the phosphorescence emitting dopant which is contained in a largest density among the phosphorescence light emitting dopants in the light emitting layer A is in the range of 4 weight % to 20 weight %; and another one of the light emitting layers, designated as a light emitting layer B, is provided at a nearer position to a cathode than the light emitting layer A; and the light emitting layer B emits an emission light having a maximum emission wavelength of 480 nm or less.
