Abstract
Provided are an organometallic complex providing highly efficient phosphorescence and an organic electroluminescence device using the same. 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.
