Abstract: A substrate for a display device and a display device including the same are disclosed. The substrate includes a first thin-film transistor including an oxide semiconductor layer, a second thin-film transistor spaced apart from the first thin-film transistor and including a polycrystalline semiconductor layer, and a storage capacitor including at least two storage electrodes. One of the at least two storage electrodes is located in the same layer and is formed of the same material as a gate electrode of the second thin-film transistor that is disposed under the polycrystalline semiconductor layer, and another one of the at least two storage electrodes is located above the polycrystalline semiconductor layer with at least one insulation film interposed therebetween. Accordingly, lower power consumption and a larger area of the substrate are realized.

Abstract: A display apparatus having a connection electrode which crosses a bending area may be provided. The connection electrode may be disposed on a device substrate including a bending area between a display area and a pad area. The connection electrode may connect the display area and the pad area across the bending area. The connection electrode may have a stacked structure of the lower connecting electrode and the upper connecting electrode. A light-emitting device, an encapsulating element and a touch electrode may be sequentially stacked on the display area of the device substrate. The upper connecting electrode may include the same material as the touch electrode. Thus, in the display apparatus, the disconnection of the connection electrode due to bending stress and external impact may be reduced.
