ABSTRACT:
A droplet ejection apparatus for forming a functional film on a substrate is disclosed. The apparatus has a droplet ejection head having a nozzle forming surface in which a plurality of nozzles are formed. Droplets of a functional film forming composition are ejected from the nozzles onto the substrate. The nozzles form a plurality of nozzle rows that extend linearly. The nozzles of each of the nozzle rows are spaced at substantially equal intervals in such a manner that the pitch between each adjacent pair of the nozzles becomes greater than the diameter of a coating dot formed by each of the droplets on the substrate and smaller than the double of the diameter of each coating dot. The nozzle rows are arranged in such a manner as to form a zigzag pattern with the nozzles of the nozzle rows.
