Abstract
Provided is a method of cleaning a flexible substrate. The method includes the steps of: preparing a flexible substrate and detaching an impurity adhered to both surfaces of the flexible substrate using rotating first rollers disposed on the both surfaces of the flexible substrate; and removing the impurity by transferring the impurity from the first roller to a second roller using the rotating second roller having a relatively higher adhesion than the first roller.
