Title:
ORGANIC ELECTROLUMINESCENT ELEMENT, ILLUMINATION DEVICE, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/063690
Kind Code:
A1
Abstract:
By means of using an organic electroluminescent element material that enables drying at a low temperature and in a short time period and that has high tolerance to external factors such as water and oxygen, a long-lasting organic electroluminescent element, illumination device, and display device are provided. The organic electroluminescent element has at least one organic-compound layer sandwiched between a positive electrode and a negative electrode, and is characterized by at least one of the organic-compound layers containing nanoparticles, and by the nanoparticles containing a light-emitting dopant compound and a light-emitting host compound having a 0-0 band of phosphorescence that is at or below 460 nm.
