According to an exemplary embodiment of the present disclosure, a display apparatus includes a substrate including a first edge, a second edge disposed opposite to the first edge, and a third edge connecting the first edge to the second edge. The display apparatus further includes a wire extending along at least one of the first, second, and third edges of the substrate and having an inner edge. The inner edge has a first portion and a second portion. The first portion is substantially parallel to the third edge, and the second portion extends in a direction crossing the first portion and extends away from a center of the substrate. The display apparatus further includes a first insulating layer covering a portion of the substrate. The portion of the substrate covered by the first insulating layer is closer to the center of the substrate than the wire, the first insulating layer covers the first portion of the wire and a part of the second portion of the wire, and a first end of the first insulating layer is disposed on the wire. The display apparatus further includes a second insulating layer covering the first insulating layer and having a second end disposed on the wire. At least one of a first distance between the first end and the second end covering the first portion of the wire or a second distance between the first end and the second end covering the second portion of the wire alternates between a first value and a second value along the first or second portions of the wire. The first value and the second value are different from each other.

In an exemplary embodiment, only one of the first distance and the second distance alternates between the first value and the second value along one of the first and second portions of the wire in a direction toward the center of the substrate.
