Electronic device including metal patterns in margin area

An electronic device comprising:

• a display panel including a pixel area configured to display an image, a margin area surrounded by the pixel area, and a hole area surrounded by the margin area,
• wherein the display panel includes:
• a base layer;
• a circuit element layer including a buffer layer on the base layer, at least one transistor on the buffer layer, at least one insulating layer on the buffer layer, and a first metal pattern on the at least one insulating layer and overlapping the margin area;
• a display element layer including a first electrode connected to the at least one transistor, a second electrode, and an organic layer between the first electrode and the second electrode, wherein an electrode opening corresponding to the margin area is defined by an edge of the second electrode;
• and
• an encapsulation layer on the display element layer,
• wherein a hole passing through the display panel is defined in the hole area, and
• wherein an insulation opening is overlapped between an edge of the second electrode defined the electrode opening and the first metal pattern in the at least one insulating layer, and exposes a portion of the buffer layer.
