Abstract: A display device, by detecting a subpixel which is a defect by using an electronic fuse electrically connected to a driving transistor disposed on a subpixel and performing a repair, a display device being capable of detecting a defect and repairing by a circuit driving of the subpixel can be provided. Thus, even in the case that a repair by a physical method is not possible according to types of the display device, by detecting a defect of the subpixel and performing a repair, an image quality deterioration due to the defect of the subpixel can be prevented.
