Summary:PROBLEM TO BE SOLVED: To achieve a highly reliable ink jet device causing no deterioration in film thicknesses variation between adjacent pixels even when a number of nozzles to which a drive signal is set to be controlled is decreased.SOLUTION: In an ink jet device, one pixel is coated by discharges from a plurality of nozzles, the nozzles are divided into two nozzle groups. A nozzle of a first nozzle group is connected to a control device setting a drive signal for each nozzle, while a nozzle of a second nozzle group is connected to a control device setting a common drive signal.
