A display panel includes: a substrate defining an opening therein; a plurality of light-emitting diodes in a display area surrounding the opening; an encapsulation layer on the plurality of light-emitting diodes, the encapsulation layer including at least one inorganic encapsulation layer and at least one organic encapsulation layer; a first partition wall and a second partition wall in a non-display area between the opening and the display area in a direction from the display area to the opening; and a plurality of grooves defined above the at least one inorganic insulating layer in the non-display area. The at least one inorganic insulating layer is on the substrate. At least one of the plurality of grooves is defined between the first partition wall and the second partition wall and is covered with the organic encapsulation layer.
