1. A display device, comprising:
a substrate including a top surface and a bottom surface opposite to the top surface, wherein the substrate has an opening that passes from the top surface of the substrate to the bottom surface of the substrate;
a plurality of display elements disposed on the top surface of the substrate in a display area, wherein the display area entirely surrounds the opening of the substrate in a plan view;
an encapsulation layer disposed on the plurality of display elements and including a first inorganic encapsulation layer, an organic encapsulation layer on the first inorganic encapsulation layer, and a second inorganic encapsulation layer on the organic encapsulation layer;
a first groove located in the non-display area between the opening of the substrate and the display area; and
a planarization layer, wherein the first and second inorganic encapsulation layers extend toward the non-display area, and the planarization layer is disposed on the second inorganic encapsulation layer in the non-display area and overlaps the first groove;
wherein:
the first groove is defined in a multi-layered structure that includes a first layer and a second layer on a top surface of the first layer,
the first layer includes an organic insulating material, and
the second layer includes a first tip that laterally protrudes toward the first groove beyond a first edge where the top surface of the first layer and a first lateral surface of the first layer that faces the first groove meet, and
wherein an insulating layer is disposed on a top surface of the second layer.
