ABSTRACT:
An ink jet head22of linear form which consists of a plurality of nozzles27arranged as a nozzle row28is provided in an ink jet device for manufacture of a color filter. Filter element material13from the nozzles27which differ from the motherboard12is discharged four superimposed times by the plurality of nozzles27, and is formed to a predetermined film thickness upon a single filter element3. It is possible to prevent the occurrence of undesirable deviations in film thickness between different ones of the filter elements3, so that it is possible to flatten and make even the optical transparency characteristic of the resulting color filter1.
