Title:
ORGANIC LIGHT-EMITTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/047853
Kind Code:
A1
Abstract:
Provided is an organic light-emitting device having: an exciton generation layer which contains a compound, in which the difference between the lowest excited singlet energy level and the lowest excited triplet energy level is 0.3 eV or less, or an exciplex that emits delayed fluorescence; and a light-emitting layer which contains a light-emitting material. This organic light emitting device has a high efficiency and a long lifetime.
