Abstract
A method for manufacturing a color filter colors a large number of filter elements on a substrate respectively in a predetermined color. A filter element is colored while an ink-jet head nozzle and the filter element are aligned. The method comprises a detection step of detecting the position of the filter element, a correction step of correcting a relative position of the filter element and a discharge nozzle for discharging coloring material, based on position information of the filter element detected at the detection step, so that the filter element and the discharge nozzle are aligned, and a coloring step of coloring the filter element by discharging the coloring material by the discharge nozzle.
