DROPLET EJECTION APPARATUS, METHOD FOR FORMING FUNCTIONAL FILM, APPARATUS FOR FORMING LIQUID CRYSTAL ALIGNMENT FILM, METHOD FOR FORMING LIQUID CRYSTAL ALIGNMENT FILM OF LIQUID CRYSTAL DISPLAY, AND LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide a droplet ejection apparatus for efficiently forming a uniform functional film at a low cost, a method for forming the functional film, an apparatus for forming a liquid crystal alignment film, a method for forming a liquid crystal alignment film of a liquid crystal display, and the liquid crystal display.;SOLUTION: The droplet ejection apparatus for forming the functional film on a substrate has a droplet ejection head having a nozzle forming surface 26 in which a plurality of nozzles are formed. Droplets of a functional film forming composition are ejected from the nozzles onto the substrate. The droplet ejection apparatus which is characterized in that the plurality of nozzles form nozzle rows that extend linearly, wherein the nozzles of each of the nozzle rows are spaced at substantially equal intervals in such a manner that the pitch M between each adjacent pair of the nozzles becomes greater than the diameter L of a coating dot formed by each of the ejected droplets of the functional film forming composition on the substrate 2 and smaller than the double of the diameter of each coating dot, and the nozzle rows are arranged in such a manner as to form a zigzag pattern with the nozzles of a plurality of nozzle rows, and the method for forming the functional film by using the droplet ejection apparatus, are provided.;COPYRIGHT: (C)2007,JPO&INPIT
