DISPLAY DEVICE

A display device includes a substrate including an active area, a hole area disposed within the active area and having a through hole disposed therein, and a disconnection area surrounding the hole area; and a plurality of disconnection structures disposed on the substrate in the disconnection area, wherein each of the plurality of disconnection structures includes, a lower layer, an intermediate layer disposed on the lower layer and having a width smaller than that of the lower layer, and an upper layer disposed on the intermediate layer and having a width greater than that of the intermediate layer, thereby penetration of moisture or oxygen from the through hole into the active area is minimized.
