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.

Abstract: An organic light-emitting display device including an encapsulating layer for coupling an encapsulating substrate to a device substrate in which a light-emitting structure is formed, is provided. The encapsulating layer can include a lower encapsulating layer and an upper encapsulating layer which are sequentially disposed on the light-emitting structure. The lower encapsulating layer can be in direct contact with the light-emitting structure. The upper encapsulating layer can include a moisture-absorbing material. Thus, in the organic light-emitting display device, the permeation of external moisture can be prevented, and the heat dissipation can be improved.
