LIGHT-EMITTING DEVICE EQUIPPED WITH ORGANIC ELECTROLUMINESCENT ELEMENT, PROCESS FOR PRODUCTION OF THE LIGHT-EMITTING DEVICE, AND ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE EQUIPPED WITH THE LIGHT-EMITTING DEVICE

摘要

Disclosed is a light-emitting device (20) having at least one organic El element (15) mounted thereon. In the organic El element (15), at least an anode (3), a cathode (5) and an organic layer (4) comprising a light-emitting layer are laminated on a substrate (2). An electrically conductive layer (6) having a higher work function than that of the cathode (5) is provided on the cathode (5), and an external substrate (1) is in contact with the lower surface of the substrate (2). Another external substrate (8) is arranged further above the electrically conductive substrate (6), and both the external substrate (8) and the external substrate (1) seal the organic El element (15). The electrically conductive layer (6) is connected to the external substrate (8) through a wiring (7a), an external electrically conductive layer (9) having a lower work function than that of the wiring (7a) and having a heat dissipating structure is connected to the wiring (7a). The anode (3) is connected to the external substrate (8) through the wiring (7b).
