Abstract:
A color filter manufacturing method for forming plural filter elements on a substrate by discharging ink from a discharge nozzle to the substrate and coloring in predetermined colors, said method comprising the steps of:obtaining distance information corresponding to a distance between the substrate and the discharge nozzle in a discharge direction of the ink which is discharged towards the substrate from the discharge nozzle;adjusting the distance between the substrate and the discharge nozzle to a predetermined distance based on the result of said distance information obtaining step;correcting a relative position of a filter element and the discharge nozzle in a direction substantially perpendicular to the discharge direction of the ink so that the filter element and the discharge nozzle are aligned; andforming the plural filter elements by discharging the ink from the discharge nozzle onto the substrate with the distance between the substrate and the discharge nozzle being adjusted in said distance adjusting step to the predetermined distance,wherein said adjusting step is performed before said correcting step.
