ABSTRACT:
The invention is directed to organic light emitting diodes (OLEDs) and methods of manufacturing the same. According to embodiments of the invention, an improved electron transport layer (ETL) reduces the driving voltage and current consumption of the OLED, and increase luminous efficiency and lifespan. The OLED includes a first electrode, an organic layer on the first electrode and including an emission layer (EML) and an ETL, and a second electrode on the organic layer.
