摘要:
A coating method and a coating apparatus which is suitable for stably forming a coating on the surface of a flat sheet member, and a method of manufacturing coated sheets such as a color filter. The coating method comprises the steps of supplying a coating liquid to a coating liquid discharging apparatus having a coating liquid discharging slit by means of a coating liquid feeder, relatively moving at least either the coating liquid discharging apparatus or a member to be coated and forming a coating having a predetermined thickness on the member. A coating start portion of the member is stopped at a place at which it opposes the coating liquid discharging slit of the coating liquid discharging apparatus, and discharge of the coating liquid from the coating liquid discharging slit is started. After a coating liquid bead which is in touch with both of the front end opening of the coating liquid discharging slit and the coating start portion of the member is formed, relative movement of at least either the coating liquid discharging apparatus or the member is started. By the coating method, discharge of the coating liquid is started when the member stops relative to the coating liquid discharging slit, and after the formation of the coating liquid bead is confirmed, the member is relatively moved in a state that the coating liquid bead remains stable. Therefore, the coating start position can be correctly determined, and a coating can be formed highly accurately.
