Light-emitting device and method for manufacturing the same
Abstract:
The present invention provides an organic light-emitting element where a lower electrode, an organic compound layer and an upper electrode are laminated on a substrate, wherein the upper electrode of the organic EL element is formed by a laminate of at least a conductive first inorganic film, a conductive organic film and a conductive second inorganic film, in order to suppress the occurrence of dark spot, so that the occurrence of pinholes in the upper electrode leading to dark spots is suppressed. Here, pinholes refer to holes in the upper electrode that penetrate upper electrode from the organic compound layer underneath to the atmosphere above.
