Abstract: A display apparatus including a display panel including a base substrate and a first pad electrode on a first pad portion of the base substrate, a flexible substrate connected to the first pad portion, and a driving chip electrically connected to the flexible substrate. The flexible substrate includes a first film layer, a first wiring layer on the first film layer and comprising a plurality of wirings, a second film layer on the first wiring layer, and a second wiring layer on the second film layer and comprising a plurality of wirings. The wirings of the second wiring layer include a first_first wiring and a first_second wiring, the first_first wiring and the first_second wiring extend in a same direction along a same line and are spaced from each other by a gap therebetween. The gap is at an edge of the base substrate in a plan view.

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.
