Light-emitting device

摘要

The present invention provides a technique for performing film-forming of a cathode comprising a metallic with a good adhesion, as well as a light-emitting device producing a good image to be displayed. An EL element is fabricated to have a structure in which an electron transport layer comprising a low molecular weight film is provided on a luminescent layer ( 104 ) comprising a polymer film and a cathode ( 106 ) comprising a metallic film is provided on the resultant electron transport layer. With such structure, occurrence of delamination or a dark spot derived from inferior adhesion of the cathode ( 106 ) can be prevented to obtain the light-emitting device producing a good image quality.
