Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2015/198563
Kind Code:
A1
Abstract:
[Problem] To provide a highly efficient, low drive voltage organic electroluminescent element with long service life, by combining, as materials for highly efficient, highly durable organic electoluminescent elements, different materials for organic electroluminescent elements having excellent hole and electron injection and transport performance, electron blocking capacity, stability and durability in thin-film form, in such a manner that said materials are able to effectively exhibit their respective properties. [Solution] An organic electroluminescent element having, in the following order, at least a positive electrode, a hole transport layer, a light-emitting layer, an electron transport layer and a negative electrode, wherein the hole transport layer contains an aryl amine compound represented by general formula (1), and the electron transport layer contains a compound having an anthracene ring structure represented by general formula (2).
