    Abstract: A display apparatus including an auxiliary electrode are disclosed. The display apparatus includes a contact area between pixel areas. The auxiliary electrode is within the contact area. A planarization layer covering the auxiliary electrode includes an inclined surface overlapping with the contact area and an upper surface extending from the inclined surface. A connection electrode covering the inclined surface and the upper surface of the planarization layer is connected to the auxiliary electrode. A light-emitting device on each pixel area has first and second electrodes and a light-emitting layer. The light-emitting layer and the second electrode extends onto the connection electrode. The light-emitting layer exposes a portion of the connection electrode by a reflow pattern, and the second electrode is in contact with the portion of the connection electrode exposed by the light-emitting layer. Thus, a process of connecting the second electrode and the connection electrode may be simplified.

    Abstract: A touch display apparatus is provided. The touch display apparatus may include touch electrodes on an encapsulating layer covering light-emitting devices. An auxiliary line crossing a display area in which the light-emitting devices are disposed may be disposed on the encapsulating layer. The auxiliary line may be electrically connected to a power voltage supply line at the outside of the display area. Each of the light-emitting devices may include a first emission electrode, a light-emitting layer and a second emission electrode, which are stacked on an emission area defined by a bank insulating layer. The second emission electrode of each light-emitting device may be electrically connected to the auxiliary line on the bank insulating layer. Thus, in the touch display apparatus, a luminance deviation due to a voltage drop may be prevented or at least reduced.
