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 plane and is formed of the same material as gate electrodes of the first thin-film transistor and the second thin-film transistor, and another one of the at least two storage electrodes is located in the same plane and is formed of the same material as source and drain electrodes of the first thin-film transistor and the second thin-film transistor. Accordingly, lower power consumption and a larger area of the substrate are realized.

Abstract: Disclosed are an organic light emitting display device to improve an aperture ratio, and a method of manufacturing the same. The organic light emitting display device includes a plurality of contact holes overlapping an anode of an organic light emitting element in each sub-pixel region, wherein conductive films connected through at least one of the contact holes are transparent, thus allowing regions, where the contact holes are formed, to be used as light emitting regions, thereby improving an aperture ratio.

Abstract: A thin and lightweight display device is disclosed. An organic light-emitting display device having a touch sensor is configured such that an outer planarization layer fills a space between a plurality of dams, thereby preventing a short circuit between routing lines in the space between the dams, and such that touch electrodes are disposed on an encapsulation structure for encapsulating a light-emitting element, with the result that an additional bonding process is not required, whereby the process is simplified and cost is reduced.

Abstract: Disclosed are a display device and a method of manufacturing the same. In the disclosed display device, a pad cover electrode disposed on a pad area comes into contact with an upper surface and a side surface of a pad electrode since a planarization layer is disposed on an active area excluding the pad area, which may prevent contact failure between the pad cover electrode and a conductive ball. In addition, in the display device, a first electrode, which is connected to a thin film transistor via a pixel connection electrode, is formed via the same mask process as the planarization layer so that it has a line width similar to that of the planarization layer and overlaps the planarization layer, which may simplify a structure and a manufacturing process.
