Abstract
Provided are a highly efficient phosphorescent organometallic complex and an organic electroluminescent (EL) device using the same. The organometallic complex can be used in the formation of an organic layer of the organic EL device, and can emit light in a red wavelength range as a highly efficient phosphorescent material. The organic EL device using the organometallic complex can exhibit high brightness and a low driving voltage.
