Abstract: A display panel includes a peripheral region adjacent to a display region. The display region includes a hole peripheral region, and a recessed region is overlapped with the hole peripheral region. The display panel also includes a barrier layer with a penetrating opening overlapped with the recessed region, a circuit layer on the barrier layer and including a transistor and insulating layers, and a device layer including an organic light emitting area coupled to the circuit layer. In addition, a module hole is overlapped with the hole peripheral region and penetrates the base substrate, and a first groove is overlapped with the hole peripheral region and corresponds to a portion of the base substrate that is recessed from a top surface of the barrier layer and that encloses the module hole. The insulating layers include inorganic layers and an organic layer having side portions enclosing the module hole.

Abstract: A display device includes a base layer including first and second portions, and a third portion between the first and second portions and configured to be bent, folded, or rolled, a light emitting element layer on one surface of the base layer at the first portion, and including light emitting elements, a circuit board on the one surface of the base layer at the third portion, and electrically connected to the light emitting elements, protective patterns spaced apart from each other on another surface of the base layer, including a resin, and also including first protective patterns spaced apart from each other on the other surface of the base layer at the first portion, and at least one second protective pattern on the other surface of the base layer at the second portion, and at least one of a heat dissipation layer or a cushion layer below the protective patterns.
