Title: ORGANIC ELECTROLUMINESCENT ELEMENT AND LIGHTING DEVICE
Abstract:
This organic electroluminescent element comprises, between a first electrode and a second electrode, a light-emitting unit including at least a light-emitting layer made from an organic compound. The organic electroluminescent element comprises at least one light-emitting unit including a light-emitting layer formed of a red light-emitting layer which emits red light having a peak wavelength in the red wavelength range. The red light obtained by light emission from the light-emitting unit has a peak wavelength in the red wavelength range of 590-640 nm. The difference between the peak wavelength of the red light and the dominant wavelength of the red light is 10 nm or less.
