Document Type and Number:
WIPO Patent Application WO/2014/185063
Kind Code:
A1
Abstract:
Provided is an organic electroluminescent element provided with at least three light-emitting units. A plurality of light-emitting units (1) comprise: one or more short-wavelength light-emitting units (1S) having a weighted average light-emission wavelength λs of 380nm to less than 550nm; and a plurality of long-wavelength light-emitting units (1L) having a weighted average light-emission wavelength λs of 550nm to 780nm. The number of long-wavelength light-emitting units is greater than the number of short-wavelength light-emitting units.
