Abstract:
1. An apparatus to form a color filter, comprising: an ink-jet head having a plurality of nozzles; and a controller configured to control the ink-jet head selectively inclined at a first predetermined angle with respect to the color filter and moving in a first lengthwise direction of the color filter and selectively inclined at a second predetermined angle with respect to the color filter and moving in a second lengthwise direction of the color filter to eject ink toward the color filter, wherein the ink-jet head is disposed to move in the first and second lengthwise directions which are parallel to each other in adjacent working regions to eject the ink toward the color filter, and the first and second predetermined angles are substantially symmetrical with each other with respect to an arbitrary line parallel to the lengthwise direction, and the ink-jet head is symmetrically arranged with an ink-jet head mirror-image in adjacent working regions.
