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.
