Abstract
A color filter is colored using a head unit comprising a head mounting portion whereupon multiple ink jet heads are mounted and a position adjusting device capable of adjusting the distance between the ink jet heads by moving the ink jet heads in the nozzle row direction such that this distance is a natural multiple of the nozzle pitch. This configuration allows for easy positional adjustment between the head units even in the event that the number of heads used is increased, so the advantages of reduction in manufacturing time due to the increase in heads used can be sufficiently achieved. Preventing the amount of time necessary for positioning an increased number of heads from becoming prolonged provides for a color filter manufacturing apparatus whereby manufacturing time can be sufficiently reduced.
