A vacuum roll-to-roll device includes: a first chamber; a second chamber neighboring the first chamber; a shutter disposed between the first chamber and the second chamber; a sealing member attached to the shutter; and a roll-type substrate which moves from the first chamber to the second chamber through the sealing member. A thickness of a lateral side of the roll-type substrate decreases in a direction toward an edge thereof.
