An object is to provide an organometallic complex that can emit red light. Another object is to provide an organometallic complex having high emission efficiency. Still another object is to provide an organometallic complex that can emit red light with high luminous efficiency. The present invention provides an organometallic complex having a structure represented by the following general formula (G1′).
In the formula, Ar represents an aryl group having 6 to 25 carbon atoms; R
1
represents any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an alkoxy group having 1 to 4 carbon atoms; R
2
to R
8
each represent any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, and a halogen group; at least one of pairs R
3
and R
4
, R
4
and R
5
, and R
5
and R
6
may be bound to each other to form a ring; and M represents a central metal of Group 9 elements and Group 10 elements.

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.
