摘要：
In an organic EL element having a transparent conductive electrode and a cathode opposed to the transparent conductive electrode, the cathode includes a film of a rare earth element that can be sputtered. The film of the rare earth element having a low work function, for example, a LaB6 film, can be formed uniformly over a wide area on an electron injection layer by a rotary magnet sputtering apparatus.
