Zusammenfassung:An organic light emitting display (OLED) device includes a substrate, a semiconductor element on the substrate, a planarization layer on the semiconductor, and a light emitting structure on the planarization layer. The planarization layer includes a contact hole exposing a portion of the semiconductor and a plurality of grooves surrounding the contact hole. The light emitting structure is electrically connected to the semiconductor element via the contact hole.
