When an ink for display panels for e.g., a plasma display panel is applied by an ink-jet method using an ink coater to form a functional layer such as a reflective layer or a phosphor layer, uneven adhesion of the ink is prevented. An ink ejected through a nozzle of an ink coater contains a powdery material used as a material of a functional layer of a display panel, water or a solvent having a free miscibility with water, a binder of a water-soluble resin, and a plasticizer. The plasticity of the ink is maintained even after the coating. Therefore the applied ink is leveled and uneven adhesion of the ink is suppressed. |
