Abstract: A display device according to embodiments of the present disclosure includes at least one groove formed in an organic file disposed on a substrate. As a result, it is possible to discharge, or delay the movement of, moisture generated in a manufacturing process of the display device, or gas remaining in an organic film. Thus the display quality and lifetime of the display device can be improved.

Abstract: A display device includes a display panel having a through-hole and a rough pattern around the through-hole, an optical electronic device positioned to at least partially overlap with the through-hole, and a metal pattern positioned in a valley of the rough pattern. Thus, it is possible to provide a robust display device against moisture that may be introduced through the through-hole.
