The object of the present invention is to provide a phosphor ink applying device that can apply phosphor ink in a plurality of lines to an intricately-shaped surface of a back panel of a PDP while preventing phosphor colors mixing.A valve is provided for the aperture of each nozzle of the phosphor ink applying device and the opening and closing of each valve is controlled according to the shape of the portion of the surface to which ink is to be applied. In this way, mixing of colors can be prevented on an intricately-shaped back panel such as that with auxiliary barrier ribs.
