摘要:
A light-emitting element having high emission efficiency and long lifetime is provided. By manufacturing a light-emitting device using the light-emitting element, the light-emitting device having low power consumption and long lifetime is provided. The light-emitting element is manufactured in which a light-emitting layer is included between a first electrode serving as an anode and a second electrode serving as a cathode. The light-emitting layer includes a first organic compound having a hole-transporting property, a second organic compound having an electron-transporting property, and an organometallic complex including a dibenzo[f,h]quinoxaline skeleton as a ligand. Further, a light-emitting device is manufactured using the light-emitting element.
