An organic EL device with a voltage applied across an anode and a cathode so that holes are moved in a hole transport layer and electrons are moved in an electron transport layer, and the holes and the electrons are recombined in a light emitting layer to emit light. The light emitting layer is formed of light emitting material having one or more kinds of metallic impurities. By using such a light emitting material, the decrease of light-emission luminance of the organic EL device can be suppressed.
