ABSTRACT:
It is an object of the present invention to provide a color filter manufacturing method which can make the color density of a filter uniform. In order to achieve the object, according to the present invention, there is provided a color filter manufacturing method for a color filter manufactured by forming and arranging a large number of colored filter elements on a transparent substrate, including the first discharge step of discharging a colored droplet of a first volume onto each filter element formation region on the substrate so as to form each of the filter elements, and the second discharge step of discharging a droplet of a second volume smaller than the first volume onto a position on the substrate where the droplet of the first volume has been discharged.
