Abstract
Provided is an organic electroluminescent device (organic EL device) with improved luminous efficiency, sufficiently ensured driving stability, and a simple construction. The organic electroluminescent device includes an anode, an organic layer, and a cathode laminated on a substrate, in which at least one organic layer selected from the group consisting of a light-emitting layer, a hole-transporting layer, an electron-transporting layer, an electron-blocking layer, and a hole-blocking layer contains a carborane compound that has at least one carborane ring with a silyl group on the carbon thereof.
