Abstract: Disclosed herein is a drum for roll-to-roll deposition to rotate about a longitudinal axis. The drum is circular in a widthwise cross-section and has a shape in which opposite longitudinal edge portions each have a narrower width than a longitudinal central portion. By using the drum for roll-to-roll deposition according to embodiments of the present disclosure, it is possible to remove wrinkles occurring on a flexible substrate when a roll-to-roll deposition process is performed. As a result, it is possible to manufacture a film roll having a deposition layer with excellent widthwise thickness uniformity.

Abstract: A touch screen panel for a display device includes layers of polymer formed on both sides of a substrate for forming driving electrodes and sensing electrodes. The substrate may be made of materials such as polyethylene terephthalate (PET). Instead of bonding a window cover made of a heavy material, layers or polymer are formed on both sides of the substrate to afford rigidity to the touch screen panel. By removing the window cover, the weight and thickness of the touch screen panel can be reduced.
