ABSTRACT:
An electroluminescent device having a structure including a light-emitting layer (4) composed of at least an organic polymer between an anode (2) and a cathode (6), includes a then film layer (5) disposed between the light-emitting layer (4) and the cathode (6), the thin-film layer suppressing unnecessary current which does not contribute to light emission.
