Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2014/104315
Kind Code:
A1
Abstract:
This electroluminescent element is characterized by comprising an anode, a cathode, and a light-emitting layer. The electroluminescent element is further characterized in that: the light-emitting layer contains a first compound and a second compound; and the first compound and the second compound are thermally-activated delayed fluorescence compounds.
