Document Type and Number:
WIPO Patent Application WO/2022/209956
Kind Code:
A1
Abstract:
An organic electroluminescent element (1) which is provided with a first electrode (3), a second electrode (4), and a light emitting layer (5) that is arranged between the first electrode (3) and the second electrode (4), wherein: the light emitting layer (5) contains at least one organic material and at least one perovskite compound; the triplet energy of the organic material is higher than the emission energy of the perovskite compound; and the volume fraction of the organic material in the light emitting layer (5) is from 10% by volume to 99% by volume.
