    摘要： It is an object of the present invention to obtain an organometallic complex that is capable of converting an excited triplet state into luminescence, a light-emitting element that can be driven for a long time, is high in luminous efficiency, and has a favorable long lifetime, and a light-emitting device using the light-emitting element. The present invention provides a light-emitting element that has a pair of electrodes (an anode and a cathode) and a light-emitting layer between a pair of electrodes, where the light-emitting layer includes an organometallic complex represented by the following general formula (5) and one of a compound that has a larger energy gap than the organometallic complex and a compound that has a larger ionization potential and a smaller electron affinity than the organometallic complex, and provides a light-emitting device using the light-emitting device.
