Abstract: A display device includes a base layer including a display area and first and second non-display areas, a circuit device layer on the base layer and including a driving circuit unit overlapping the first and second non-display areas, a power electrode outside the driving circuit unit, and a shielding electrode connected to the power electrode and through which first through-holes are defined, a light emitting device layer on the circuit device layer and including a second electrode and a connection electrode electrically connecting the power electrode to the second electrode and through which second through-holes are defined, a thin film encapsulation layer on the light emitting device layer, and a touch sensing layer on the thin film encapsulation layer. The first and second through-holes do not overlap each other in the first non-display area, and the first and second through-holes overlap each other in the second non-display area.
