Abstract: A display apparatus is provided. The display apparatus may include a substrate hole penetrating a device substrate. A light-emitting device may be disposed on the device substrate. The light-emitting device may be spaced away from the substrate hole. A separating device may be disposed between the substrate hole and the light-emitting device. The device substrate may be in contact with the device substrate. Thus, in the display apparatus, the permeation of the moisture through the crack of the insulating layer which occurs in a process of forming the substrate hole may be prevented.

Abstract: Disclosed is a display device capable of reducing the thickness and the weigh thereof. A display device having a touch sensor realizes electrical connection of a routing line and a touch pad via an auxiliary conductive layer, which is connected to the routing line under an encapsulation unit, even if a disconnection fault occurs in the routing line, thereby achieving increased yield and reliability. In addition, through the provision of a touch sensor disposed above the encapsulation unit, a separate attachment process is unnecessary, which results in a simplified manufacturing process and reduced costs.

Abstract: Disclosed are an organic light emitting display device to improve optical efficiency and prevent deterioration in reliability of thin film transistors, and a method of manufacturing the same. The organic light emitting display device includes a mirror wall which is disposed on a substrate such that the mirror wall surrounds a light emitting area of each sub-pixel where a light emitting element is disposed, thus preventing total reflection of light produced in the light emitting element and improving optical efficiency by reflecting light travelling toward a non-emitting area to be directed to the light emitting area.

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: 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.
