Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/053398
Kind Code:
A1
Abstract:
The organic electroluminescent element (100) of the present invention comprises, on a substrate (1), electrodes (positive electrode (2) and negative electrode (8)) forming a pair and an organic functional layer (20) having at least an electron transport layer (6) and a light emitting layer (5). At least one of the electron transport layer (6) and the light emitting layer (5) contain semiconductor nanoparticles having a conduction band energy level of -5.5 - -1.5 eV.
