Abstract
An organic light emitting display device may include a substrate having a display area and a non-display area at least partially surrounds the display area, a pixel structure disposed in the display area on the substrate, a via insulating layer disposed in the non-display area on the substrate and having a contact hole, a lower pad disposed on the via insulating layer and a connecting structure. Here, the connecting structure may include a flexible substrate disposed on the lower pad, an upper pad disposed between the flexible substrate and the lower pad, and an upper dummy pad spaced apart from the upper pad in a first direction on a bottom surface of the flexible substrate.
