Abstract: 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.

Abstract: An organic light-emitting display apparatus includes a substrate, pixels, a pixel defining layer (PDL), a first via layer, a second via layer, first lines, and a second line. The pixels are arranged on the substrate in a first direction (D1) and a second direction (D2) intersecting one another, and include organic light-emitting diodes (OLEDs). The OLEDs include pixel electrodes (PEs). The PDL covers edges of the PEs and defines light-emitting regions via openings partially exposing the PEs. The first and second via layers are between the PEs and the substrate. The first lines extend in the D2 between the first via layer and the substrate. The second line is between the second and first via layers. The second line at least partially extends around the light-emitting regions. The second line contacts the first lines through via holes. Each via hole is provided every two pixels arranged in the D2.
