Display panel

A display panel comprising:

• a substrate comprising a first area, a display area, and a middle area between the first area and the display area;
• a transistor in the display area;
• a display element comprising a pixel electrode, an intermediate layer, and an opposite electrode, the pixel electrode being electrically connected to the transistor, the intermediate layer being on the pixel electrode, and the opposite electrode being on the intermediate layer;
• a first organic insulating layer between the transistor and the pixel electrode and a second organic insulating layer over the first organic insulating layer;
• and
• a plurality of grooves in the middle area and disconnecting at least one organic material layer of the intermediate layer, each of the plurality of grooves having an undercut structure,
• wherein at least one of the plurality of grooves is defined in a first multi-layer, the first multi-layer comprising a first lower layer and a first upper layer, the first lower layer comprising a first sub-lower layer and a second sub-lower layer under the first sub-lower layer, and the first upper layer being on the first lower layer.
