Abstract

Disclosed are color filter producing method and apparatus in which while an ink-jet head having a plurality of nozzles arranged in a first direction and a substrate are relatively scanned in a second direction perpendicular to the first direction, the ink-jet head ejects ink onto the substrate, so that filter elements arranged in the first direction have the same color, and filter elements adjacent from each other in the second direction have different colors. Three production conditions, the amount of ink ejected at one time by the nozzles, the number of times of the main scans and the sub-scanning distance, are changed in accordance with the width of each filter element of an obtained color filter. As a result, it is possible to provide a method whereby, even when the type of color filter to be produced is changed, the time required for the preparation accompanying the change can be reduced, and multiple types of color filters can be easily produced at a low cost, and to provide an apparatus therefor.
