Abstract:
A production device to produce an organic EL display includes a solution in which a light emitting material is dissolved, and a flying electrode to receive solution from the container. A voltage is applied between the tip of the flying electrode and an electrically conductive material of an organic EL substrate to form an electrostatic field, and the tip of the flying electrode and the organic EL substrate are shifted relative to one another in at least one of a perpendicular direction and a horizontal direction. With this arrangement, the solution is formed into a stringy beam from the tip of the flying electrode to 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.
