7. A method of cleaning a sealing unit, for use in a coating apparatus,
wherein the coating apparatus includes: -
a slit nozzle provided with a discharge port at a lower side thereof and configured to discharge a coating liquid from the discharge port; a sealing unit formed to extend along a longitudinal direction of the discharge port and including a top surface which is brought into contact with the discharge port to seal the discharge port; and a solvent reservoir configured to retain a solvent, the method comprising; exposing at least a portion of the sealing unit making contact with the discharge port from the solvent retained in the solvent reservoir; bring the discharge port into contact with the top surface of the sealing unit such that the discharge port is sealed by the sealing unit; and immersing the top surface of the sealing unit into the solvent retained in the solvent reservoir.
