摘要： An ink jet head 22 of linear form which consists of a plurality of nozzles 27 arranged as a nozzle row 28 is provided in an ink jet device for manufacture of a color filter. Filter element material 13 from the nozzles 27 which differ from the motherboard 12 is discharged four superimposed times by the plurality of nozzles 27, and is formed to a predetermined film thickness upon a single filter element 3. It is possible to prevent the occurrence of undesirable deviations in film thickness between different ones of the filter elements 3, so that it is possible to flatten and make even the optical transparency characteristic of the resulting color filter 1.

摘要： A pressurizing chamber 1 is formed as a recess by half etching of a silicon single-crystal substrate 2. A nozzle communicating hole 6 through which the pressurizing chamber 1 is connected to a nozzle opening 5 is formed as a through hole which is smaller in width than the pressurizing chamber 1. The pressurizing chamber 1 is connected to the nozzle opening 5 in the other face via the nozzle communicating hole 6 while reducing the volume of the pressurizing chamber 1 to a degree as small as possible. The silicon single-crystal substrate is used as a member constituting a spacer so that an ink drop of a reduced ink amount suitable for high density printing flies with high positioning accuracy.

摘要： Connection electrodes are formed to be located on the same plane as discrete internal electrodes, and to be exposed to the rear face while being insulated from the discrete internal electrodes. With the conductive relationship between the connection electrodes and common electrodes, the resistance of the common internal electrodes is reduced, and the size of the fixed area is also reduced accordingly.
