Abstract
Provided are an organometallic complex providing highly efficient phosphorescence and an organic electroluminescence device using the organometallic complex represented by Formula 1: MLL'where M is Ir, Os, Pt, Pb, Re, Ru or Pd, L and L′ are different bidentate ligands, m is 1, 2 or 3, and n is 3−m. The organometallic complex can be used to form an organic layer of the organic electroluminescence device, efficiently emits light of a wavelength corresponding to red light, and has high brightness and low operating voltage.
