ORGANIC LIGHT-EMITTING ELEMENT AND LIGHT-EMITTING DEVICE WITH THE ORGANIC LIGHT-EMITTING ELEMENT

摘要

The present invention provides a white organic light-emitting element high in the emission efficiency. In particular, the invention provides a white organic light-emitting element that has an emission spectrum having peaks in the respective wavelength regions of red color, green color and blue color and is high in the emission efficiency. It is preferable to use an electron transport material between a first emission region and a second emission region and more preferable to use a hole block material.
