ABSTRACT:
A chelate complex having as its central metal tungsten which is an inexpensive metal and which is a heavy atom is applied to an organic light emitting element, thereby obtaining an organic light emitting element capable of converting the triplet excitation energy into light emission. By applying the organic light emitting element using this metal complex, an inexpensive light emitting device which is bright but consumes little power can be provided as well as an electric appliance using the light emitting device.
