ABSTRACT:
In a method for manufacturing an organic electroluminescence device of the present invention, when an anode, an organic layer including a light-emitting layer, and a cathode are sequentially formed on a substrate to manufacture an organic electroluminescence device, as the cathode, an alkali metal or a compound thereof is deposited and then a low electric resistance metal is deposited. The alkali metal and compound thereof is caused to diffuse in the low electric resistance metal and the organic layer.
