Abstract: A display device includes a display panel and an input sensing unit disposed on the display panel. The display panel includes a base layer, a first signal line, a light emitting element, a first encapsulation inorganic layer, and a signal pad. The first signal line overlaps a display area and a non-display area and is connected to a transistor disposed in the display area. The first encapsulation inorganic layer is disposed on a second electrode of the light emitting element and overlaps the display area and the non-display area. The signal pad is electrically connected to the first signal line and disposed in the non-display area. The signal pad is connected to the first signal line through a first contact hole defined through the first encapsulation inorganic layer.
