1. A color filter manufacturing apparatus for manufacturing a color filter by ejecting ink from an ink-jet head onto a plurality of color element regions, each of which being segmented by partition members on a substrate, comprising:

  • an ink-jet head having a plurality of nozzles which are arranged in a first direction and adapted to eject ink, the plurality of nozzles including a plurality of groups of nozzles corresponding to a plurality of colors of the color filter, respectively;

    moving means for moving the substrate or said ink-jet head in a second direction substantially perpendicular to the first direction;

    ink amount setting means for setting an amount of ink to be applied to each of the color element regions, wherein the amount of ink is set once per one color filter;

    applying means for applying ink to different positions, in substantially the first direction, of each of the color element regions on the substrate, by ejecting the same color ink from different nozzles of a group of nozzles of said ink-jet head, corresponding to the color of the color element region, during one movement by said moving means; and

    control means for controlling to apply ink of a color of the color element region in accordance with the amount of ink set by said ink amount setting means, to each color element region by repeating an operation of ink applications performed by said applying means so that each color element region is filled with ink applied in plural movements by said moving means, each color element region having a different color from neighboring color element regions arranged in the second direction, wherein ink is applied to neighboring color element regions in the second direction by said applying means such that the neighboring color element regions arranged in the second direction have different colors from each other.
