Abstract

Disclosed is an organometallic compound represented by a following Chemical Formula 1. The organometallic compound acts as a dopant of a light-emitting layer of an organic light-emitting diode. Thus, operation voltage of the diode is lowered, and luminous efficiency and lifespan thereof are improved: [Chemical Formula 1] Ir(L<A>)<m>(L<B>)<n> where in the Chemical Formula 1, L<A> represents a main ligand, and is one selected from a group consisting of Chemical Formula 2-1, Chemical Formula 2-2, and Chemical Formula 2-3, L<B> denotes an ancillary ligand represented by a Chemical Formula 3, each of m and n denotes a number of the ligands bound to Ir (iridium), and m is 1, 2 or 3, and n is 0, 1 or 2, and a sum of m and n is 3.
