PURPOSE:To provide an organic thin film EL element which effectively exhibits low power property, and is improved in driving stability and physical stability in manufacturing process. CONSTITUTION:As a negative electrode 14, an alloy in which 0.01-5 mole % of scandium and 0.01-0.3 mole % of alkali metal are contained in a metal having a work function of 4eV or more is used. The negative electrode 14 preferably has a film thickness of about 1-30nm. An aluminium alloy 50nm or more in film thickness which contains 0.1-5 mole % of silicon, copper, scandium, or manganese may be used on the negative electrode 14 as a negative electrode protecting layer 15. |
