摘要： An organometallic compound includes a hexadentate ligand bonded to a metal atom (M1). An energy level (E3MC) of a 3MC state (triplet metal centered state) of the organometallic compound is higher than an energy level (E3MLCT) of a 3MLCT state (triplet metal-to-ligand charge transfer state) of the organometallic compound.

摘要： A display device includes a red pixel, a green pixel, and a blue pixel comprising a plurality of transistors and an organic light emitting element. The organic light emitting element has a value of a temperature sensitive factor (TSF) in a range of about 0.25×10−1 Cd·m2/V to about 0.51×10−1 Cd·m2/V as shown in a following equation:
