It is an object to provide a novel bipolar organic compound. In
particular, it is an object to provide a bipolar organic compound
excellent in thermal stability. Further, it is another object to provide
a bipolar organic compound which is electrochemically stable. A
quinoxaline derivative represented by a general formula (1) is provided.
Further, since the quinoxaline derivative represented by the general
formula (1) is bipolar, the use of the quinoxaline derivative of the
present invention allows fabrication of a light-emitting element and a
light-emitting device with a low driving voltage and low power
consumption. Furthermore, a light-emitting element with high luminous
efficiency can be obtained. ##STR00001##
