Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2013/118812
Kind Code:
A1
Abstract:
This organic electroluminescent element has, between an opposite positive electrode and negative electrode, at least two hole transport layers, and a light-emitting layer, in order, and is characterized in that one of the hole transport layers contains a compound of a specific structure having a fluorene structure at the center and is not adjacent to the light-emitting layer. In this organic electroluminescent element, the hole transport layer can be thicker, optical film thickness can be adjusted, and element performance can be improved.
