ABSTRACT:
An object is to provide a novel quinoxaline derivative. Another object is to provide a light-emitting element with low driving voltage. Another object is to provide a light-emitting element with low power consumption. Another object is to provide a light-emitting device and an electronic device with low power consumption by using such a light-emitting element. A quinoxaline derivative which has a structure in which at least one of carbon at a 2-position and carbon at a 3-position of quinoxaline, and carbon of 1,3,4-oxadiazole ring are bound via an arylene group is provided.
