Abstract: A rollable display device is provided. The rollable display device may include a flexible display panel. The flexible display panel may be wound or unfolded on a panel roller according to a user's request in order to improve portability and space usability. The rollable display device may further comprise a transparent protection film disposed on a display surface of the flexible display panel. In the rollable display device, the transparent protection film may be spaced away from the flexible display panel. Thus, the rollable display device may minimize damage to the flexible display panel due to the external impact.

Abstract: An organic light-emitting display device includes an organic insulating layer such as an over-coat layer, a bank insulating layer and a capping layer. The organic insulating layer extends onto a non-display area of a lower substrate. The organic insulating layer is in contact with an encapsulating layer having a moisture-absorbing material on the non-display area of the lower substrate. Thus, the organic light-emitting display may block a path of permeating the moisture by the organic insulating layer.

Abstract: A touch display device for preventing the occurrence of a short circuit between routing lines is disclosed. The touch display device includes a dam forming a boundary with an encapsulation unit covering a light-emitting element, and the dam is formed such that the height thereof in a region that overlaps routing lines, which are connected to touch electrodes disposed on the encapsulation unit, and the height thereof in a region that does not overlap the routing lines are different from each other, thereby preventing the occurrence of a short circuit between the routing lines.
