Abstract: An organic light emitting display device includes a substrate. A buffer layer is disposed on the substrate. The buffer layer includes a first opening exposing an upper surface of the substrate in a bending region. Pixel structures are positioned in a pixel region on the buffer layer. A fan-out wiring is positioned in the peripheral region and the pad region on the insulation layer structure such that the upper surface of the substrate and the first portion of the buffer layer are exposed. A passivation layer is disposed on the fan-out wiring, side walls of the insulation layer structure adjacent to the bending region, and the first portion of the buffer layer. The passivation layer includes a third opening exposing the upper surface of the substrate in the bending region. A connection electrode is positioned in the bending region on the substrate.

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.
