Abstract: A display device includes a display unit and a roller configured to wind or unwind the display unit, and comprising a flat portion, a first curved portion extending from the flat portion, and a second curved portion extending from the first curved portion toward the flat portion, in which a radius of curvature of the first curved portion is larger than a radius of curvature of the second curved portion, and a radius of curvature of the display unit wound around the second curved portion is larger than the radius of curvature of the second curved portion, thus the second curved portion is formed to support the display unit so that the display unit is not curved with a small radius of curvature between the first curved portion and the flat portion.

Abstract: A display device according to an exemplary aspect of the present disclosure may include a display panel including a non-display area, a back cover supporting the display panel on one surface of the display panel, a roller for winding or unwinding the display panel and the back cover and side covers covering a portion of the non-display area of the display panel and a portion of a side surface of the back cover corresponding thereto, and including a plurality of unit side covers to thereby support the non-display area of the display panel when the roller is wound. Thus, stress generated during rolling can be reduced and accordingly, it is possible to prevent cracks and damage to the GIP unit.

Abstract: A display device according to an example of the present disclosure includes a lower substrate divided into an active area and a non-active area, an upper substrate disposed above the lower substrate, a flexible film connected to a pad area of the lower substrate in the non-active area, a first sealing film disposed in the pad area and having at least one open hole, and a second sealing film disposed on a top surface of the flexible film and a side surface of the upper substrate. By this configuration, moisture which may permeate through a side surface of the display device can be more effectively blocked.
