ABSTRACT:
An organic EL device according to the present invention has a layered structure in which a hole injection electrode (anode), a hole injection layer, a hole transport layer, a light emitting layer, a hole blocking layer, an electron injection layer, and an electron injection electrode (cathode) are layered in this order on a substrate. The light emitting layer is composed of a host material and an emitting dopant. A compound for light emitting device which is an organic material is employed for the emitting material. The compound for light emitting device is a metal complex employing a ligand having a substituent containing boron.
