The anode (12) comprises silver which is a metal with high reflectance or an alloy including silver, and the thin film layer for hole injection (13) comprises chromium oxide or the like. Light generated in the luminescent layer (15C) is multiply reflected between the anode (12) and the semi-transparent electrode (16A) to be emitted from the cathode (16). As the reflectance of the anode (12) is enhanced, the light generated in the luminescent layer (15C) can be efficiently emitted.
