Abstract:
A coating method for a coating liquid comprising:preparing a coating surface which has a plurality of regions that are to be coated with said coating liquid; providing a plurality of storage chambers under atmospheric pressure in which said coating liquid is stored in respective amounts that enable the coating surfaces of said corresponding regions to be coated to substantially a same coating thickness; disposing said corresponding regions at undersides of said storage chambers; and applying said coating liquid on the coating surfaces of said corresponding regions by pushing said coating liquid stored in said storage chambers by said atmospheric pressure, wherein said storage chambers are provided so that said storage chambers extend in a direction perpendicular to the coating surfaces of said corresponding regions, said storage chambers have equal cross-sectional areas and different respective lengths along the extension direction, and amounts of said coating liquid that are proportional to said lengths are respectively stored in said respective storage chambers, and wherein said storage chambers are aligned in a specified direction that passes through a center of said corresponding regions, and wherein said lengths of said storage chambers are respectively greater from the center of said corresponding regions to an outer periphery of said corresponding regions.
