Abstract
Provided are an organic EL device practically satisfactory in terms of its light-emitting characteristics, driving voltage, and durability, and a compound for an organic EL device to be used in the device. The organic EL device has a structure in which an anode, a plurality of organic layers including a light-emitting layer, and a cathode are laminated on a substrate, and the organic EL device contains, in at least one organic layer selected from the light-emitting layer, a hole-transporting layer, an electron-transporting layer, a hole-blocking layer, and an electron-blocking layer, an adamantane compound having at least one triarylborane structure in a molecule thereof as the compound for an organic EL device.
