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.
