Abstract: A display apparatus includes a first power supply voltage line in a non-display area and including a first conductive layer, a first organic layer on the first conductive layer, and a second conductive layer on the first organic layer, a second power supply voltage line in the non-display area and including a third conductive layer spaced apart from the first conductive layer, and a fourth conductive layer on the first organic layer which is on the third conductive layer, a first dam portion adjacent to the first power supply voltage line, a second dam portion adjacent to the first dam portion, and a third dam portion between the first power supply voltage line and the first dam portion. The fourth conductive layer includes an opening exposing an upper surface of the first organic layer between the first power supply voltage line and the second dam portion.

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.
