Abstract: Embodiments of the present disclosure are related to a display device, as arranging a storage capacitor and an active pattern disposed on a subpixel by using an active layer that a semiconductor layer and a conductive layer are laminated, an area of the storage capacitor can be increased efficiently and methods can be provided to use an area overlapped with a contact-hole located on the active pattern as an area of the storage capacitor. Furthermore, as a location of the contact-hole is adjusted easily, by making the contact-hole not to be disposed on an area adjacent to a driving transistor, a size of the driving transistor can be increased and an aperture ratio of the subpixel can be improved.

Abstract: An organic light emitting display panel and an organic light emitting display device including the display panel that includes a buffer layer disposed on a first conductive layer, and including a first contact hole overlapping a part of the first conductive layer, an active layer disposed on the buffer layer, a first insulating film disposed on the active layer and the buffer layer, and including a second contact hole overlapping the first contact hole, a second insulating film disposed over the first insulating film, and including a third contact hole overlapping a part of each of the first contact hole and the second contact hole, and a third conductive layer disposed on the second insulating film, and contacting a part of the second conductive layer through the second contact hole. The third contact hole does not overlap with the active layer. The organic light emitting display panel including a high-capacity storage capacitor and the organic light emitting display device including the display panel can be provided.
