Abstract: Disclosed is a novel organometallic compound in which a main ligand (LA) has a fused ring structure including a thiophene group. The organometallic compound acts as a dopant of a phosphorescent light-emitting layer of an organic light-emitting diode. Thus, an operation voltage of the diode is lowered, and luminous efficiency and a lifespan thereof are improved.
