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.
