Abstract:
A device for producing an organic EL display comprising;means for storing a solution in which a light emitting material is dissolved; means for feeding said solution to a tip of a flying electrode; and means for applying a voltage between the tip of the flying electrode and an electro-conductive material of an organic EL substrate and thereby forming an electrostatic field, wherein the tip of the flying electrode and the organic EL substrate are relatively shifted with respect to one another in at least one of a perpendicular direction and a horizontal direction, and wherein said solution is formed into the form of a stringy beam from the tip of the flying electrode to let it fly onto the organic EL substrate, thereby injecting the solution into a concavity formed and surrounded by banks on the organic EL substrate, and forming red, green and blue light emitting layers.
