Material discharging apparatus and method for producing color filters, liquid crystal and electroluminescent devices

摘要

The present invention seeks to to shorten the scanning time with an ink jet head for forming a pattern of filter elements of a color filter, picture element pixels of an EL device, or the like. An apparatus for producing a color filter including a plurality of filter elements arranged on a substrate. The apparatus includes a plurality of heads 20 each having a nozzle row 28 having a plurality of nozzles 27 arranged, an ink supply device for supplying a filter element material to the heads 20, a carriage 25 supporting the heads 20 arranged thereon, a main scanning driving device for moving the carriage 25 by main scanning in the X direction, and a sub-scanning driving device for moving the carriage 25 by sub-scanning in the Y direction. The carriage 25 supports the plurality of heads 20 each of which is inclined at an in-plane inclination angle &thetas;.
