1. A display device comprising:
a substrate having an opening;
a thin film transistor on a display area of the substrate and comprising a semiconductor layer and a gate electrode, the display area at least partially surrounding the opening;
a display element electrically connected to the thin film transistor;
a first groove in a non-display area between the opening of the substrate and the display area and defined in a multi-layer, the first groove having a shape concaved into the multi-layer, wherein the multi-layer comprises a lower layer on the substrate and at least one layer on the lower layer, and the at least one layer and the lower layer comprise materials that have different etch selectivities;
a second groove in the non-display area and defined in the multi-layer, the second groove having a shape concaved into the multi-layer;
a partition wall in the non-display area, wherein the partition wall is between the first groove and the second groove; and
an encapsulation layer covering the display element and comprising a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer,
wherein the display element comprises a pixel electrode, an opposite electrode, and an intermediate layer between the pixel electrode and the opposite electrode, and
wherein at least one organic layer of the intermediate layer has a plurality of portions that are separated from each other by the first groove.
