Abstract: Disclosed is an organic light-emitting display device having a touchscreen in which the configuration of a pad unit and a circuit board connected to the pad unit is simplified, resulting in bonding stability and an improved form factor of the device, and a method of manufacturing the same. In the organic light-emitting display device having the touchscreen in which a touch electrode is directly provided on an encapsulation layer, a touch pad and a display pad are disposed parallel to each other on the same side so as to be connected to a flexible printed circuit board with a difference in height therebetween. Thereby, increased bonding reliability and an increased effective display area are achieved.

Abstract: Disclosed are a display device that enables reduction in thickness and weight and a method of manufacturing the same. The display device having a touch sensor includes a touch sensing line and a touch driving line, which are formed on an encapsulation unit and intersect each other with a touch insulation layer interposed therebetween. The touch insulation layer intersects with any one of the touch sensing line and the touch driving line, which may result in the simplified structure. In addition, touch electrodes are disposed on the encapsulation unit, which may make a separate attachment process be unnecessary, resulting in a simplified manufacturing process and reduced costs.

Abstract: Discussed is a display device including a substrate including a first region and a second region surrounding the first region, a plurality of first subpixels on the first region of the substrate, and a plurality of second subpixels on the second region of the substrate. The first region includes a transmission portion adjacent to the plurality of first subpixels. Each of the first and second subpixels includes a first electrode, a first common layer, an organic emission layer, a second common layer, and a second electrode stacked in order. The first and second common layers are located in succession in the first and second subpixels.

Abstract: A display device capable of reducing a non-display area is disclosed. The disclosed display device includes a first through hole not overlapping with an organic cover layer surrounding at least one hole area disposed within an active area, and a second through hole passing through a substrate. Accordingly, it is possible to minimize a bezel area, which is a non-display area, and to prevent damage to a light emitting stack caused by a stripping process.

Abstract: A display device capable of reducing a non-display area includes a substrate hole surrounded by light emitting elements, and a moisture penetration preventing layer disposed between an inner dam surrounded by the light emitting elements and the substrate hole. Accordingly, it is possible to prevent damage to light emitting stacks caused by external moisture or oxygen. Since the substrate hole is disposed within an active area, a reduction in non-display area is achieved.
