White Light Emitting Organic Electroluminescence Element, Display and Illuminator

摘要

A white light emitting organic electroluminescent element comprising two electrodes having therebetween one or more constituting layers including a light emission layer, the one or more constituting layers comprising at least two phosphorescent compounds, wherein at least one of the phosphorescent compounds is a green light emitting ortho metalated complex; and a spectral ratio of the green light emitting ortho metalated complex in ae emission spectral distribution in a range of 400-800 nm is not less than 60%.
