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.
