Abstract
A method of manufacturing an organic EL element according to the present invention comprises the steps of forming pixel electrodes (801), (802), (803) on a transparent substrate (804) and forming on the pixel electrodes by patterning luminescent layers (806), (807), (808) made of an organic compound by means of an ink-jet method. According to this method, it is possible to carry out a high precise patterning easily and in a short time, thereby enabling to carry out optimization for a film design and luminescent characteristic easily as well as making it easy to adjust a luminous efficiency.
