摘要：
This invention relates to a highly precise and efficient color filter producing apparatus, which is provided with at least a set of drawing heads for respectively generating ink jets of red, green and blue colors, movement means for moving, with a substrate on which a color filter is to be formed by drawing with said ink jets, in a plane having a predetermined distance from the drawing heads, displacement detection means for detecting relative displacement between the substrate and the drawing heads in directions of six freedoms, means for detecting the reaching position on the substrate of the ink jet discharged from the drawing head, and alignment means for effecting alignment between the substrate and the drawing heads in directions of six freedoms, based on the results of detection of the reaching position and of the relative displacement between the substrate and the drawing head in directions of six freedoms.
