Abstract:
A method of manufacturing a color filter by coloring each filter element with a plurality of discharge inks, said method comprising the steps of:relatively scanning an ink-jet head over a substrate in at least first and second scanning operations; and performing a coloring operation by changing discharging positions of inks onto respective filter elements in the first scanning operation with respect to the discharging positions of inks in the second scanning operation, wherein, in the first scanning operation, ink is discharged with predetermined spacing such that a plurality of inks applied on one filter element are partially joined to each other and form colored portions and non-colored portions on the one filter element, and in the second scanning operation, ink is further discharged between the plurality of ink discharging positions in the first scanning operation such that an area of the non-colored portions on the one filter element is decreased, and each filter element is filled with the plurality of inks discharged in the plurality of scanning operations.
