ABSTRACT:
The surface of an anode is made flat by wiping/cleaning of the present invention. Thereafter, an organic compound layer and a cathode are formed to produce a light emitting element. In this way, the distance between the anode and the cathode becomes constant. Therefore, when an electric field is applied to the light emitting element, the current density in the organic compound layer becomes uniform. Thus, it is possible to prevent the deterioration of the organic compound layer and improve the element characteristic thereof.
