1. A display apparatus comprising a display area and a peripheral area outside the display area, the display apparatus comprising:
a first conductive layer on a substrate in the peripheral area and comprising a first hole;
a second conductive layer on the first conductive layer in the peripheral area;
a first insulating layer on the second conductive layer in the peripheral area;
a display element in the display area and comprising a first electrode, a second electrode facing the first electrode, and an emission layer between the first electrode and the second electrode,
wherein the second electrode comprises a portion in the peripheral area, and
wherein a first contact area of a plurality of contact areas at which the portion of the second electrode contacts the second conductive layer overlaps the first hole of the first conductive layer, and a second contact area of the plurality of contact areas contacts the first conductive layer;
a second insulating layer between the first conductive layer and the second conductive layer; and
a third insulating layer between the second insulating layer and the first electrode in the display area.
