摘要： A display apparatus includes a substrate, a wire having an inner edge including first and second portions, a first insulating layer covering a portion of the substrate, and a second insulating layer. The portion of the substrate covered by the first insulating layer is closer to a center of the substrate than the wire, the first insulating layer covers a part of 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 second insulating layer covers the first insulating layer and has a second end disposed on the wire. A distance between the first end and the second end covering the first portion of the wire is different from a distance between the first end and the second end covering the second portion of the wire.
