Abstract

The present invention relates to coating methods and coating apparatus suitable for the stable production of coatings on the flat surface of sheet substrates, and methods for manufacturing coated sheet products such as color filters.
An embodiment of the coating method according to the present invention is a coating method wherein a coating liquid feeder supplies coating liquid to a coating liquid applicator having a coating liquid discharge slot, with at least either the coating liquid applicator or a substrate to be coated being moved relatively one to the other to form a coating with a predetermined thickness on the substrate, comprising the steps of: keeping at rest the substrate at a position where the start-of-coating line of the substrate is in register with the coating liquid discharge slot of the coating liquid applicator; commencing discharge of the coating liquid through the coating liquid discharge slot; forming a coating liquid bead which is in contact with both an exit aperture portion of the coating liquid discharge slot and the start-of-coating line of the substrate; and subsequently commencing movement of at least either the coating liquid feeder or the substrate relatively one to the other.
A coating method of this embodiment makes it possible to accurately determine the start-of-coating line and form a high accuracy coating, because by this method, after discharge of the coating liquid starts while the substrate to be coated is still at rest in register with the coating liquid discharge slot and the formation of the coating liquid bead is assured, the substrate is moved relatively to the coating liquid discharge slot while rendering the coating liquid bead stable.
