1. A method of manufacturing an organic EL device, comprising:
- forming first electrodes on or above a substrate;
forming at least one luminescent layer having a certain color and made of an organic compound on or above the first electrodes by an ink-jet method; and
forming a second electrode opposing the first electrodes, the formation of said at least one luminescent layer by means of the ink-jet method being performed by discharging a luminescent material composition from a nozzle toward the substrate, the luminescent material composition serving as luminescence function and carrier transfer function in the formed at least one luminescent layer.

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.
