An object of the present invention is to increase the work function of an anode to increase hole injection efficiency, to lower the device driving voltage, to improve the life characteristics and chromaticity stability during continuous driving, and to increase the resistance as much as possible. Provided is a method for manufacturing a suppressed organic electroluminescence element. A method for manufacturing an organic electroluminescent element formed by providing an organic light emitting layer (3) for controlling light emission between an anode (6) and a cathode (1). After cleaning the surface of the anode 6 so that the contact angle of the surface of the anode 6 with water becomes 10 ° or less, a surface treatment is performed to increase the work function of the surface of the anode 6 by 0.5 eV or more. Thereafter, the organic light emitting layer 3 and the cathode 1 are formed on the anode 6. [Selection diagram] Fig. 1 |
