Abstract
A method of manufacturing a color filter having a plurality of colored pixels on a substrate by discharging an ink from an ink-jet head having a plurality of ink discharging nozzles while performing relative movement of the ink-jet head and the substrate, includes the step of dividing the plurality of ink discharging nozzles for discharging the ink having a same color into a plurality of nozzle groups, each nozzle group including every N nozzles, with N being a positive integer. In coloring one substrate by performing the relative movement a plurality of times, an ink discharging operation is performed such that inks are discharged by using only one nozzle group of the plurality of nozzle groups in the plural relative movements, and ink discharging nozzles which are used in a subsequent relative movement always include all of, or part of, ink discharging nozzles which have been used in a previous relative movement.
