    Abstract: A display device may include a base substrate including display and peripheral regions adjacent to each other, an organic light emitting device, and an encapsulation member. A module hole, a first blocking groove, and a second blocking groove may be defined in the base substrate. The module hole may be defined in the display region to penetrate the base substrate from a front surface to a rear surface. The first and second blocking grooves may be provided to enclose the module hole. A distance from the rear surface of the base substrate to a top surface of the encapsulation member between the first and second blocking grooves is smaller than that in a region outside the second blocking groove.

    Abstract: A display panel including a glass substrate having an opening area, and a display area at least partially surrounding the opening area; a thin film transistor on the display area including a semiconductor layer and a gate electrode; a display element electrically connected to the thin film transistor; a multi-layer including an insulating layer and a lower insulating layer. The insulating layer is between the glass substrate and the display element and the lower insulating layer is between the glass substrate and the insulating layer; and a thin-film encapsulation layer covering the display element including an inorganic encapsulation layer and an organic encapsulation layer. The multi-layer includes a first groove between the opening area and the display area. A first width of a portion of the first groove in the lower insulating layer is greater than a second width of a portion of the first groove in the insulating layer.
