Abstract: An organic light emitting display (OLED) device includes a substrate comprising a display region and a peripheral region. The OLED device further includes a conductive layer disposed in the peripheral region on the substrate and including an opening portion exposing at least a portion of the substrate, the conductive layer having an undercut shape. The OLED device additionally includes an insulation layer disposed on the conductive layer, the insulation layer including an opening that exposes the opening portion. The OLED device further includes a common layer disposed in both the display region and the peripheral region on the insulation layer and on the substrate exposed by the opening portion. The common layer disposed on the substrate exposed by the opening portion is spaced apart from the common layer disposed on the insulation layer.
